A quote
The wise man, the seeker after wisdom, is bound closely, indeed, to his body, but he is an absentee so far as his better self is concerned, and he concentrates his thoughts upon lofty things. Bound, so to speak, to his oath of allegiance, he regards the period of life as his term of service. He is so trained that he neither loves nor hates life; he endures a mortal lot, although he knows that an ampler lot is in store for him.
