Siddhartha Gautama (fl. ca. 500 B.C.E.), also called Shakyamuni (“sage of the Shakya tribe”), is best known as the Buddha (“enlightened one”). He was a contemporary of Mahavira and came from the same warrior social class. At age twenty-nine, unsatisfied with his life of comfort and troubled by the suffering he saw around him, he left home to become a wandering ascetic. He traveled south to the kingdom of Magadha, where he studied with yoga masters, but later took up extreme asceticism. According to tradition, while meditating under a bo tree at Bodh Gaya, he reached enlightenment. After several weeks of meditation, he preached his first sermon, urging a “middle way” between asceticism and worldly life. For the next forty-five years, the Buddha traveled through the Ganges Valley, propounding his ideas, refuting his adversaries, and attracting followers. Probably because he refused to recognize the divine authority of the Vedas and dismissed sacrifices, he attracted followers mostly from among merchants, artisans, and farmers, rather than Brahmins.

In his first sermon the Buddha outlined his main message, summed up in the Four Noble Truths and the Eightfold Path. The Four Noble Truths are as follows: (1) pain and suffering, frustration, and anxiety are ugly but inescapable parts of human life; (2) suffering and anxiety are caused by human desires and attachments; (3) people can understand these weaknesses and triumph over them; and (4) this triumph is made possible by following a simple code of conduct, the Eightfold Path. The basic insight of Buddhism is thus psychological. The deepest human longings can never be satisfied, and even those things that seem to give pleasure cause anxiety because we are afraid of losing them. Attachment to people and things causes sorrow at their loss.

Buddhism differed from Brahmanism and later Hinduism in that it ignored the caste system. Everyone, noble and peasant, educated and ignorant, male and female, could follow the Eightfold Path. Moreover, the Buddha was extraordinarily nondogmatic. In his view, there was no harm in honoring local gods or observing traditional ceremonies, as long as one remembered the goal of enlightenment and did not let sacrifices become snares or attachments. The willingness of Buddhists to tolerate a wide variety of practices aided the spread of the religion.

The Buddha’s followers transmitted his teachings orally until they were written down in the second or first century B.C.E. These scriptures are called sutras. The form of monasticism that developed among the Buddhists was less strict than that of the Jains. Buddhist monks moved about for eight months of the year (except the rainy season), begging for their one meal a day, but they could bathe and wear clothes. Within a few centuries Buddhist monks began to overlook the rule that they should travel. They set up permanent monasteries, generally on land donated by kings or other patrons. Orders of nuns also appeared, giving women the opportunity to seek truth in ways men had traditionally used. The main ritual that monks and nuns performed in their monastic establishments was the communal recitation of the sutras. Lay Buddhists could aid the spread of the Buddhist teachings by providing food for monks and support for their monasteries, and they could pursue their own spiritual progress by adopting practices such as abstaining from meat and alcohol. (See “Individuals in Society: Sudatta, Lay Follower of the Buddha.”)

Because Buddhism had no central ecclesiastical authority, early Buddhist communities developed several divergent traditions and came to stress different sutras. One of the most important of these, associated with the monk-philosopher Nagarjuna (fl. ca. 100 C.E.), is called Mahayana, or “Great Vehicle,” because it was a more inclusive form of the religion. One branch of Mahayana taught that reality is empty (that is, nothing exists independently of itself). Another branch held that ultimate reality is consciousness, that everything is produced by the mind.

Just as important as the metaphysical literature of Mahayana Buddhism was its devotional side, influenced by the religions then prevalent in Central Asia, such as Zoroastrianism (see “The Religion of Zoroaster” in Chapter 2). The Buddha became deified and was placed at the head of an expanding pantheon of other Buddhas and bodhisattvas (boh-dih-SUHT-vuhz). Bodhisattvas were Buddhas-to-be who had stayed in the world after enlightenment to help others on the path to salvation. The Buddhas and bodhisattvas became objects of veneration. With the growth of Mahayana, Buddhism attracted more and more laypeople.

Buddhism remained an important religion in India until about 1200 C.E. By that time it had spread widely through East, Central, and Southeast Asia. After 1200 C.E. Buddhism declined in India, losing out to both Hinduism and Islam, and the number of Buddhists in India today is small. Buddhism never lost its hold in Nepal and Sri Lanka, however, and today it is also a major religion in Southeast Asia, Tibet, China, Korea, and Japan.
