Bhagavad Gita
The Gita posits the existence of an individual self (Atman or Soul) and the supreme self (Brahman or Supreme Soul) within each being. The dialogue between the prince and his charioteer has been interpreted as a metaphor for an immortal dialogue between the human self and God. The text covers the philosophy of Yoga in terms of Gyan (Knowledge) yoga, Bhakti (devotion) yoga, Karma (action) yoga, and Rāja (governance) yoga,.
