The Bhagavad Gita (; Sanskrit: भगवद्गीता, IPA: [ˌbʱɐɡɐʋɐd ˈɡiːtɑː], romanized: bhagavad-gītā, lit. 'God's song'), often referred to as the Gita (IAST: gītā), is a Hindu scripture, dated to the second or first century BCE, which forms part of the epic Mahabharata. It is a synthesis of various strands of Indian religious thought, including the Vedic concept of dharma (duty, rightful action); samkhya-based yoga and jnana (knowledge); and bhakti (devotion). It holds a unique pan-Hindu influence as the most prominent sacred text and is a central text in Vedanta and the Vaishnava Hindu tradition.
