[edit] The Four Noble Truths
Main article: The Four Noble Truths
The Buddha taught that in life there exists sorrow / suffering which is caused by desire and it can be cured (ceased) by following the Noble Eightfold Path (Sanskrit: Ārya 'aṣṭāṅga Mārgaḥ , Pāli: Ariyo Aṭṭhaṅgiko Maggo). This teaching is called the Catvāry Āryasatyāni (Pali: Cattāri Ariyasaccāni), the "Four Noble Truths".

Suffering: Birth is suffering, aging is suffering, illness is suffering, death is suffering; union with what is displeasing is suffering; separation from what is pleasing is suffering; not to get what one wants is suffering; in brief, the five aggregates subject to clinging are suffering.
The cause of suffering: The desire which leads to renewed existence (rebirth).
The cessation of suffering: The cessation of desire.
The way leading to the cessation of suffering: The Noble Eightfold Path;
The Four Noble Truths was the topic of the first sermon given by the Buddha after his enlightenment[3], which was given to the five ascetics with whom he had practiced austerities.

The Four Noble Truths were originally spoken by the Buddha, not in the form of a religious or philosophical text, but in the form of a common medical prescription of the time.

The Noble Eightfold Path

 
The eight-spoked Dharmachakra. The eight spokes represent the Noble Eightfold Path of Buddhism. According to a saying attributed in some traditions to the Buddha, if a person does not follow the goal of Total Realization, one lives one's life like a preoccupied child playing with toys in a house that is burning to the ground.[4]
The Noble Eightfold Path is the way to the cessation of suffering, the fourth part of the Four Noble Truths. In order to fully understand the noble truths and investigate whether they were in fact true, the Buddha recommended that a certain path be followed which consists of:

Right Viewpoint - Realizing the Four Noble Truths (samyag-dṛṣṭi, sammā-diṭṭhi)
Right Values - Commitment to mental and ethical growth in moderation (samyak-saṃkalpa, sammā-saṅkappa)
Right Speech - One speaks in a non hurtful, not exaggerated, truthful way (samyag-vāc, sammā-vācā)
Right Actions - Wholesome action, avoiding action that would do harm (samyak-karmānta, sammā-kammanta)
Right Livelihood - One's job does not harm in any way oneself or others; directly or indirectly (weapon maker, drug dealer, etc.) (samyag-ājīva, sammā-ājīva}
Right Effort - One makes an effort to improve (samyag-vyāyāma, sammā-vāyāma)
Right Mindfulness - Mental ability to see things for what they are with clear consciousness (samyak-smṛti, sammā-sati)
Right Meditation - State where one reaches enlightenment and the ego has disappeared (samyak-samādhi, sammā-samādhi)
The word samyak means "perfect". There are a number of ways to interpret the Eightfold Path. On one hand, the Eightfold Path is spoken of as being a progressive series of stages through which the practitioner moves, the culmination of one leading to the beginning of another, whereas others see the states of the 'Path' as requiring simultaneous development. It is also common to categorize the Eightfold Path into prajñā (Pāli paññā, wisdom), śīla (Pāli sīla, virtuous behaviour) and samādhi (concentration).

 Bodhi

Bodhi is a title given in Buddhism to the specific awakening experience attained by the Buddha. When used in a generic sense, a buddha is generally considered to be a person who discovers the true nature of reality through years of spiritual cultivation, investigation of the various religious practices of his time, and meditation. This transformational discovery is called bodhi (literally, "awakening" — more commonly called "enlightenment").

After attainment of Bodhi, it is believed one is freed from the cycle of saṃsāra: birth, suffering, death and rebirth. Bodhi is attained only by the accomplishment of the pāramitās (perfections), when the Four Noble Truths are fully grasped, and when all karma has reached cessation. At this moment, all greed (lobha), hatred (Pali dosa), delusion (moha), ignorance (Sanskrit avidyā, Pāli avijjā), craving (Sanskrit [[tṛṣṇā]], Pāli taṇhā) and belief in that which is not the self (anātmān, Pāli anāttā) are extinguished. Bodhi thus implies understanding of anātman (Pāli anatta), the absence of ego-centeredness. All schools of Buddhism recognise three types of Bodhi. They are Śrāvakabodhi (Pāli: Sāvakabodhi), Pratyekabodhi (Pāli: Paccekabodhi) and Samyaksambodhi (Pāli: Sammāsambodhi), the perfect enlightenment by which a Bodhisattva becomes a fully enlightened Buddha. The aspiration to attain the state of samyaksambodhi, known as the Bodhisattva ideal, is considered as the highest ideal of Buddhism.

Karma
Main article: Karma in Buddhism
In a discourse  the Buddha said:

“Intention, monks, is karma I say. Having willed, one acts through body, speech and mind”.
According to the Buddha the moral order rests on each individual and not on any divine being:

"Owners of their own Karma, O young man, are living beings heirs of their Karma, have karma as the wombs from which they spring, having Karma as their refuge. Karma marks of living being, making them become depraved and excellent." (Culakamma vibhanga sutta.)
In Buddhism, Karma has a specific meaning quite different from other teachings. Karma means action derived from mental intent or volition and its result (Vipaka) or its effect upon the doer of that volitional deed (be that deed one of thought, word, or physical action).

 Middle Way
The primary guiding principle of Buddhist practice is the Middle Way which was discovered by the Buddha prior to his enlightenment (bodhi). The Middle Way or Middle Path is often described as the practice of non-extremism; a path of moderation away from the extremes of self-indulgence and opposing self-mortification.

 Refuge in the Three Jewels

Acknowledging the Four Noble Truths and making the first step in the Noble Eightfold Path requires taking refuge, as the foundation of one's religious practice, in Buddhism's Three Jewels (Sanskrit: त्रिरत्न Triratna or रत्नत्रय Ratna-traya, Pali: तिरतन Tiratana). The buddha who chooses the bodhisattva path makes a vow/pledge. This is considered the ultimate expression of compassion.

The Three Jewels are:

The Buddha (i.e., Awakened One). This is a title for those who attained enlightenment similar to the Buddha and helped others to attain it. See also the Tathāgata and Śākyamuni Buddha. The Buddha could also be represented as the wisdom that understands Dharma, and in this regard the Buddha represents the perfect wisdom that sees reality in its true form.
The Dharma: The teachings or law as expounded by the Buddha. Dharma also means the law of nature based on behavior of a person and its consequences to be experienced (action and reaction).
The Sangha: This term literally means "group" or "congregation," but when it is used in Buddhist teaching the word refers to one of two very specific kinds of groups: either the community of Buddhist monastics (bhikkhus and bhikkhunis), or the community of people who have attained at least the first stage of Awakening (Sotapanna (pali) - one who has entered the stream to enlightenment). It also consists of laymen and laywomen, the caretakers of the monks, those who have accepted parts of the monastic code but who have not been ordained as monks or nuns.
The Buddha presented himself as a model and beseeched his followers to have faith (Sanskrit श्रद्धा śraddhā, Pāli saddhā) in his example of a human who escaped the pain and danger of existence. The Dharma, i.e. the teaching of the Buddha, offers a refuge by providing guidelines for the alleviation of suffering and the attainment of enlightenment. The Saṅgha (Buddhist Order of monks) provides a refuge by preserving the authentic teachings of the Buddha and providing further examples that the truth of the Buddha's teachings is attainable.

Many Buddhists believe that there is no otherworldly salvation from one's karma. The suffering caused by the karmic effects of previous thoughts, words and deeds can be alleviated by following the Noble Eightfold Path, although the Buddha of some Mahayana sutras, such as the Lotus Sutra, the Angulimaliya Sutra and the Nirvana Sutra, also teaches that powerful sutras such as the above-named can, through the very act of their being heard or recited, wipe out great swathes of negative karma.

Buddhism after the Buddha
 History of Buddhism and Buddhist councils
Soon after the parinirvāṇa (Pāli: parinibbāna, "complete extinguishment") of the Buddha, the first Buddhist council was held. As with any ancient Indian tradition, transmission of teaching was done orally. The primary purpose of the assembly was to collectively recite the teaching to ensure that no errors occur in oral transmission. In the first council, Ānanda, the Buddha's personal attendant was called upon to recite the discourses (sūtras, Pāli suttas) of the Buddha. Upāli, another disciple, recited the monastic rules (Vinaya).

 Early Buddhism
Main articles: The Second Buddhist Council and Early Buddhist schools
As the Saṅgha gradually grew over the next century a dispute arose regarding ten points of discipline. A Second Buddhist Council (traditionally believed to have taken place 100 years after the Buddha's death) was held to resolve the points at dispute. The result was that all the monks agreed that those 10 practices were unallowed according to Vinaya.

At some period after the Second Council however, the Sangha began to break into separate factions. The various accounts differ as to when the actual schisms occured: according to the Dipavamsa of the Pali tradition, they started immediately after the Second Council; the Puggalavada tradition places it in 137 AN; the Sarvastivada tradition of Vasumitra says it was in the time of Asoka; and the Mahasanghika tradition places it much later, nearly 100 BCE.

The Asokan edicts, our only contemporary sources, state that 'the Sangha has been made unified'. This apparently refers to a dispute such as that described in the account of the Third Buddhist Council at Pataliputta. This concerns the expulsion of non-Buddhist heretics from the Sangha, and does not speak of a schism.

These schisms occurred within the traditions of Early Buddhism, at a time when the Mahāyāna movement either did not exist at all, or only existed as a current of thought not yet identified with a separate school.

The root schism was between the Sthaviras and the Mahāsāṅghikas. The fortunate survival of accounts from both sides of the dispute reveals disparate traditions. The Sthavira group offers two quite distinct reasons for the schism. The Dipavamsa of the Theravāda accuses the Mahāsāṅghikas of unauthorized corruption of the texts. On the other hand, the northern lineages, including the Sarvastivada and Puggalavada (both branches of the ancient Sthaviras) attribute the Mahāsāṅghika schism to the '5 points' that erode the status of the arahant. For their part, the Mahāsāṅghikas argued that the Sthaviras were trying to expand the Vinaya; they may also have challenged what they perceived to be excessive claims or inhumanly high criteria for Arhatship. Both parties, therefore, appealed to tradition.[5] The Sthaviras gave rise to several schools, one of which was the Theravāda school.

Following (or leading up to) the schisms, each Saṅgha started to accumulate an Abhidharma, a collection of philosophical commentaries on the discourse of the Buddha. Early commentaries probably existed in the time of the Buddha as simple lists. However, as time went on and Buddhism spread further, the (perceived) teachings of the Buddha were formalized in a more systematic manner in a new Pitaka: the Abhidhamma Pitaka. Some modern academics refer to it as Abhidhamma Buddhism. Interestingly, the Mahasanghika school did not have an Abhidhamma Pitaka, which agrees with their statement that they did not want to add to the Buddha's teachings. But according to Chinese pilgrims Fa Xian (5th century CE) and Yuan Chwang (7th century CE), they had procured a copy of Abhidhamma which belonged to the Mahasanghika School.

 
Buddhist proselytism at the time of emperor Aśoka the Great (260–218 BCE).Buddhism spread slowly in India until the time of the Mauryan emperor Aśoka the Great, who was a public supporter of the religion. The support of Aśoka and his descendants led to the construction of more Buddhist religious memorials (stūpas) and to efforts to spread Buddhism throughout the enlarged Maurya empire and even into neighboring lands – particularly to the Iranian-speaking regions of Afghanistan and Central Asia, beyond the Mauryas' northwest border, and to the island of Sri Lanka south of India. These two missions, in opposite directions, would ultimately lead, in the first case to the spread of Buddhism into China, and in the second case, to the emergence of Theravāda Buddhism and its spread from Sri Lanka to the coastal lands of Southeast Asia.

This period marks the first spread of Buddhism beyond India. According to the edicts of Aśoka, emissaries were sent to various countries west of India in order to spread "Dhamma", particularly in eastern provinces of the neighboring Seleucid Empire, and possibly even farther to Hellenistic kingdoms of the Mediterranean. This led, a century later, to the emergence of Greek-speaking Buddhist monarchs in the Indo-Greek Kingdom, and to the development of the Greco-Buddhist art of Gandhāra. During this period Buddhism was exposed to a variety of influences, from Persian and Greek civilization, and from changing trends in non-Buddhist Indian religions – themselves influenced by Buddhism.

 Establishment of Theravāda Buddhism (Southern Tradition)
 Theravada
In addition to the Edicts of Aśoka, Buddhist annals compiled at a later date offer a history of the Aśokan and post-Aśokan period. Among these annals are the Dīpavaṃsa, the Mahāvaṃsa, and the Samantapāsādika of the south Indian Vibhajjavāda (Sanskrit: Vibhajyavāda) saṅgha, beside the Divyāvadāna and the Avadānaśataka from the northern Sarvāstivāda (Pāli: Sabbatthivāda) saṅgha. According to the accounts of the Vibhajjavāda, Aśoka convened a third Buddhist council (c. 250 BCE), whose purpose was to produce a definitive text of the Buddha's words. The result, according to the Vibhajjavādins, was the compilation of the version of the Tripiṭaka (Pāli: Tipiṭaka) found in the Pāli Canon.

The council also saw the formation of the saṅgha of the Vibhajjavāda ("school of analytical discourse") out of various schools of the Sthaviravāda lineage. Vibhajjavādins claim that the first step to insight has to be achieved by the aspirant's experience, critical investigation, and reasoning instead of by blind faith. This school gradually declined on the Indian subcontinent, but its branch in Sri Lanka and South East Asia continues to survive; this branch of the school is now known as Theravada. The Theravāda school claims that the Sarvāstivada and the Dharmaguptaka schools were rejected by the council, although according to other sources the Dharmaguptaka school is classified as one of the Vibhajyavādin schools. However, these schools became influential in northwestern India and Central Asia and, since their teaching is found among the scriptures preserved by the Mahāyāna schools, they may have had some formative influence on the Mahāyāna. The Sarvāstivadins have not preserved an independent tradition about the Third Council.

It was long believed in Theravāda tradition that the Pāli language is equivalent to Māgadhī, the eastern dialect of the kingdom of Magadha spoken by the Buddha. However, linguistic comparisons of the Edicts of Aśoka and the language of the Pāli canon show strong differences between the Māgadhī of the Edicts (characterized by such changes as r → l, masculine nominative singular of a-stems in -e, etc.) and Pāli. The greatest similarity to Pāli is found in a dialectal variant of the Edicts written on a rock near Girnar in Gujarat.

Decline of Buddhism in India and Central Asia
 
Buddhism was established in the northern regions of India and Central Asia, and kingdoms with Buddhist rulers such as Menander I and Kaniska. Under the rule of tolerant or even sympathetic Greco-Bactrian and Iranian Achaemenid kings, Buddhism flourished. The rulers of the Kushāna Empire adopted Buddhism, and it continued to thrive in the region under the rule of the Turk-Shāhīs.

Buddhists were briefly persecuted under the Zoroastrian priest-king Kirder. Syncretism between Zoroastrianism and Buddhism had resulted in the rise of a 'Buddha-Mazda' divinity, which Kirder treated as heresy.

The Hinayana traditions first spread among the Turkic tribes before combining with the Mahayana forms during the 2nd and 3rd centuries BCE to cover modern-day Pakistan, Kashmir, Afghanistan, eastern and coastal Iran, Uzbekistan, Turkmenistan and Tajikistan. These were the ancient states of Gandhara, Bactria, Parthia and Sogdia from where it spread to China. Among the first of these Turkic tribes to adopt Buddhism was the Turki-Shahi who adopted Buddhism as early as the 3rd century BCE. It was not, however, the exclusive faith of this region. There were also Zoroastrians, Hindus, Nestorian Christians, Jews, Manichaeans, and followers of shamanism, Tengrism, and other indigenous, nonorganized systems of belief.

From the 4th Century CE on, Hindu dynasties had achieved preeminence elsewhere in India. Even in regions of Buddhist predominance, such as the northwest (Pañjāb) and the lower Gangetic plain (Uttar Pradesh and Bengal), the Indian caste system and other characteristics of Hinduism were found. In political contests between Hindu and Buddhist kingdoms, Buddhist rulers were gradually replaced by Hindu ones. By the 4th to 5th century Buddhism was already in decline in northern India, even though it was achieving multiple successes in Central Asia and along the Silk Road as far as China.

The Buddhist states of Central Asia were weakened in the 6th century following the invasion of the White Huns and Buddhism suffered as recorded by Xuanzang. Later Buddhist regions in Central Asia came either under the sway of the Persian Sāsānids or Tibet. When the Muslim Arabs overthrew the Sāssānids they encountered Buddhists in the eastern provinces of the Persian Empire. They called them by the Persian name of butparast, literally meaning "buddha-worshipper", although the term has come to be used generally for any religion in which cult images play a role. Several high officials of the Abbāsid Caliphate, notably the Barmakids, were descended from these East Iranian Buddhists.

When Muhammad ibn Qāsim led the invasion of Sindh at the mouth of the Indus river, he was aided by some Buddhists in his campaign against their Hindu overlord, Rājā Dahir. Relations with later Iranian rulers such as the Saffarids and Samanids were more difficult; Buddhist monasteries and stūpas were not exempt from looting under Arab rule.[8]

After the disintegration of the Abbāsid Caliphate, the Muslim Turks rose to prominence among the Persian emirates that emerged in Central Asia and Afghanistan. In the 10th century CE, one of them, Mahmūd of Ghaznī, defeated the Hindō-Shāhīs and finally brought the region firmly under Muslim rule through Afghanistan and the Pañjāb. He demolished monasteries alongside temples during his raid across north-western India but left those within his domains and Afghanistan alone and al-Biruni recorded the Buddha as a prophet "burxan".

The originally pagan Turkic tribes who lived in western Central Asia converted to Islām as they came to be increasingly influenced by Persian culture. As the Turkic tribes of Central Asia battled for control of land, similarly an ideological battle waged within them as Sufis, faced with an increasing hostile environment in Arabia, moved to Transoxania and found fertile ground here for converts among the Buddhist and non-Buddhist Turkic tribes alike. Buddhism persisted, together with Christianity, Manichaeism, Zoroastrianism, and shamanism in areas to the east (modern Xinjiang) for several centuries, which did not become overwhelmingly Muslim until the 15th century CE; however, under the two-pronged onslaught Buddhism waned and over time Central Asia gradually became predominantly Muslim.

In 1215 Genghis Khan conquered Afghanistan and his horde devastated the local population indiscriminately; in 1227 after his death his conquest was divided and Chagatai established the Chagatai Khanate while Hulegu established the Il Khanate where Buddhism was the state religion across Muslim lands. In the Chagatai Khanate the Buddhist Turkic tribes slowly converted to Islam, including the occasional Khan [4]. When Tarmashirin came to power he made Islam the official religion of the region in 1326. In the Il Khanate, Hulegu and his successors Abaqa and Arghun also established Buddhism as the state religion but were hostile to the Muslims. Many mosques were destroyed and numerous stupas built; however, when Ghazan came to power in 1295 and converted he reverted the state religion to Islam and the climate became hostile towards Buddhism. Today no stupas built by the earlier Mongol Khans survive, and after Ghazan's reign little mention of Buddhism can be found in Afghanistan and Central Asia.[9]

Buddhists retained power in parts of northern India, in Kaśmīr and especially in Bengal, where the Buddhist Pāla kings ruled from the 8th-12th centuries CE. These last Buddhist strongholds played an important role in the evolution of the Vajrayāna and the transmission of that form of Buddhism to Tibet before they collapsed under assault from the Hindu Sena dynasty.

Elsewhere in India, Buddhism suffered from pressure by Hindu dynasties, such as the increasingly powerful Rajputs, as well as competition from a Hinduism that had gained ideological coherence and emotional vigor from such movements as Vedānta philosophy and Bhakti devotionalism. One symptom of increased Hindu confidence with regard to Buddhism was the identification of the Buddha as an avatāra of the Hindu god Vishnu – an identification which contradicted basic Buddhist understandings about the nature of a Buddha and of nirvāna.

In 1193, only a few decades after the fall of the Pāla kingdom, Muhammad Khiljī destroyed Nālandā, the great Buddhist university. Khiljī was one of the generals of Qutbuddīn Aybak, a subject of the Afghan Ghurids but soon to become the monarch of a Muslim sultanate at Delhi. Khiljī's march across northern India caused a precipitous decline in the fortunes of Indian Buddhism, as he destroyed Buddhist walled monasteries fortified by the Sena kings (which he thought were cities), killed the monks and burned their libraries.

After the Mongol invasions of Islamic lands across Central Asia, many Sufis also found themselves fleeing towards the newly established Islamic lands in India around the environs of Bengal. Here their influence, caste attitudes towards Buddhists, previous familiarity with Buddhism, lack of Buddhist political power or social structure along with Hinduism's revival movements such as Advaita and the rise of the syncretic bhakti movement, all contributed to a significant realignment of beliefs relegating Buddhism in India to the peripheries.

By the 13th century CE, Buddhism had become a marginal religion in central India; without a monastic infrastructure, Buddhism could not easily maintain its identity, and many Buddhists, especially in Bengal, were converted to Islām, Hinduism or left for the Himalayan foothills. In Kaśmīr Buddhism remained a significant religion down to the early 15th century, when it was displaced by Islām and Hinduism, except among the Tibetan peoples of Ladakh.

Elements of Buddhism have remained within India to the current day: the Bauls of Bengal have a syncretic set of practices with strong emphasis on many Buddhist concepts. Other areas of India have never parted from Buddhism, including Ladakh and other Himalayan regions with a primarily Tibetan population. Arunachal Pradesh and Sikkim are the other Indian states where Buddhism is practiced in great numbers. The Newars of Nepal also retain a form of Buddhism that differs from the Buddhism of Tibet. Furthermore, much of Buddhist philosophy was eventually absorbed into Hinduism.

 Main Traditions
 
Chinese Mahayana Buddhist monk lighting incense in Beijing temple.Buddhist schools are usually divided into two main branches: Theravāda Buddhism and Mahāyāna Buddhism. Vajrayāna is sometimes named as a third, but is more commonly considered a form of Mahāyāna Buddhism.

Another way of categorizing Buddhist schools follows the major languages of the extant Buddhist canons, which exist in Pāli, Tibetan (also found in Mongolian translation) and Chinese collections, along with some texts that still exist in Sanskrit and Buddhist Hybrid Sanskrit. This is a useful division for practical purposes, but does not necessarily correspond to philosophical or doctrinal divisions.

Despite the differences, there are common threads to almost all Buddhist branches:

All accept the Buddha as their teacher.
All accept the Middle Way, Dependent origination, the Four Noble Truths and the Noble Eightfold Path.
All accept that both the members of the laity and of the Sangha can pursue the path toward enlightenment (bodhi).
All accept two types of Buddha and consider Buddhahood to be the highest attainment.
