Ācārāṅga Sūtra in the context of "Śvetāmbara"

Mahavira (Mahāvīra), also known by his birth name Vardhamana (Vardhamāna), was an Indian religious reformer and spiritual leader who is considered by Jains to be the 24th and final Tirthankara (Supreme Preacher) of this age in Jainism. He is believed by historians to have lived in the 6th or 5th century BCE, reviving and reforming an earlier Jain or proto-Jain community which had likely been led by Pārśvanātha, whom Jains consider to be Mahavira's predecessor. Although the dates of Mahavira's life are uncertain and historically reliable information is scarce, and traditional accounts vary by sectarian traditions, the historicity of Mahavira is well-established and not in dispute among scholars.

According to traditional legends and hagiographies, Mahavira was born in 599 BCE to a ruling royal kshatriya Jain family of the Nāya tribe in what is now Bihar in India. According to traditional sources like the Ācārāṅga Sūtra, the Nāyas were followers of Parshvanatha, Mahavira's predecessor. Mahavira abandoned all worldly possessions at the age of about 30 and left home in pursuit of spiritual awakening, becoming an ascetic. Mahavira practiced intense meditation and severe austerities for twelve and a half years, after which he attained Kevala Jnana (omniscience). He preached for 30 years and attained moksha (liberation) when he died.
