Bhagavad Gita

In the Bhagavad Gita the soldiers of the Indian caste system were taught of the invulnerability of their soul. The writings claim that the soul of these people can never be destroyed, damaged, or harmed by anything, even death. Death, whether victorious in battle or in defeat, will grant your soul entrance to heaven. The duties of the soldiers in the caste system is to give their lives for their people and they will not have sinned. This contrasts to other philosophies such as Zarathustra and Confuciansim. Zarathustra taught its followers to enjoy what the world provided and good deeds and good thoughts were encouraged. However this does not provide the belief in a heaven after death. Similarly, Confucianism believes in the morality of man and righteousness as well as obligation to society, but it does not present a heaven or afterlife. The caste systems share the idea with Confucianism that they owe themselves to society.
