It behoveth thee not to suffer thyself to be overwhelmed with sorrow and to abandon all actions. There are thousands of mothers and fathers and sons and wives in this world. Whose are they, and whose are we? From day to day thousands of causes spring up for sorrow and thousands of causes for fear. These, however, affect the ignorant but are nothing to him that is wise. There is none dear or hateful to Time, O best of the Kurus! Time is indifferent to none. All are equally dragged by Time. Time causeth all creatures to grow, and it is Time that destroyeth everything. When all else is asleep, Time is awake. Time is irresistible. Youth, beauty, life, possessions, health, and the companionship of friends, all are unstable. He that is wise will never covet any of these. It behoveth thee not to grieve for what is universal. A person may, by indulging in grief, himself perish, but grief itself, by being indulged in, never becomes light. Ifthou feelest thy grief to be heavy, it should be counteracted by not indulging in it. Even this is the medicine for grief, viz., that one should not indulge in it. By dwelling on it, one cannot lessen it. On the other hand, it grows with indulgence. Upon the advent of evil or upon the bereavement of something that is dear, only they that are of little intelligence suffer their minds to be afflicted with grief. This is neither Profit, nor Religion, nor Happiness, on which thy heart is dwelling.
