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 (insight, knowledge); and bhakti (devotion).
