The senses have been conditioned by attraction to the pleasant and aversion to the unpleasant: a man should not be ruled by them; they are obstacles in his path. – Bhagavad Gita
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
