It is better to do thine own duty, however lacking in merit, than to do that of another, even though efficiently. It is better to die doing ones own duty, for to do the duty of another is fraught with danger. – Bhagavad Gita
Offer unto me that which is very dear to thee — which thou holdest most covetable. Infinite are the results of such an offering. – Bhagavad Gita
