Do not waste a single moment, like a warrior who, pierced to the heart by an arrow, knows he has only few minutes to live. It is now, while we are in good health and in possession of all our physical and mental faculties, that we should practice dharma.

When some great teachers of the past reflected on the rarity of human existence, they did not even feel like sleeping; they could not bear to waste a single moment. They put all their energy into spiritual practice.
