Mbh 12.174.7a

"'"The Brahmana said, 'Behold, all creatures,--the superior, the middling, and the inferior,--in consequence of their respective acts, are entangled in grief. I do not regard even my own self to be mine. On the other hand, I regard the whole world to be mine. I again think that all this (which I see) is as much mine as it belongs to others. Grief cannot approach me in consequence of this thought. Having acquired such an understanding, I do not yield either to joy or to grief. As two pieces of wood floating on the ocean come together at one time and are again separated, even such is the union of (living) creatures in this world. Sons, grandsons, kinsmen, relatives are all of this kind. One should never feel affection for them, for separation with them is certain. Thy son came from an invisible region. He has departed and become invisible. He did not know thee. Thou didst not know him. Who art thou and for whom dost thou grieve? Grieve arises from the disease constituted by desire. Happiness again results from the disease of desire being cured. From joy also springs sorrow, and hence sorrow arises repeatedly. Sorrow comes after joy, and joy after sorrow. The joys and sorrows of human beings are revolving on a wheel. After happiness sorrow has come to thee. Thou shalt again have happiness. No one suffers sorrow for ever, and no one enjoys happiness for ever. The body is the refuge of both sorrow and happiness.[501] Whatever acts an embodied creature does with the aid of his body, the consequence thereof he has to suffer in that body. Life springs with the springing of the body into existence. The two exist together, and the two perish together.[502] Men of uncleansed souls, wedded to worldly things by various bonds, meet with destruction like embankments of sand in water. Woes of diverse kinds, born of ignorance, act like pressers of oil-seeds, for assailing all creatures in consequence of their attachments.
