Dalai Lama in Beyond Religion.

"Within the scale of the life of the cosmos, a human life is no more than a tiny blip. Each one of us is a visitor to this planet, a guest, who has only a finite time to stay. What greater folly could there be than to spend this short time lonely, unhappy, and in conflict with our fellow visitors? Far better, surely, to use our short time in pursuing a meaningful life, enriched by a sense of connection with and service towards others.".  Dalai Lama in Beyond Religion.
