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
As person abandons worn-out clothes and acquires new ones, so when the body is worn out a new one is acquired by the Self, who lives within. – Bhagavad Gita
