Mbh 5.36.5b

And the tree that stands singly, though gigantic and strong and deep-rooted, hath its trunk soon smashed and twisted by a mighty wind. Those trees, however, that grow in close compact are competent owing to mutual dependence to resist winds more violent still. Thus he that is single, however, endowed with all the virtues, is regarded by foes as capable of being vanquished like an isolated tree by the wind. Relatives, again, in consequence of mutual dependence and mutual aid, grow together, like lotus-stalks in a lake. These must never be slain, viz., Brahmanas, kine, relatives, children, women, those whose food is eaten, and those also that yield by asking for protection. O king, without wealth no good quality can show itself in a person. If, however, thou art in health, thou canst achieve thy good, for he is dead who is unhealthy and ill. O king, anger is a kind of bitter, pungent, acrid, and hot drink, painful in its consequences: it is a kind of headache not born of any physical illness, and they that are unwise can never digest it. Do thou, O king, swallow it up and obtain peace. They that are tortured by disease have no liking for enjoyments, nor do they desire any happiness from wealth. The sick, however, filled with sorrow, know not what happiness is or what the enjoyments of wealth are. Beholding Draupadi won at dice, I told thee before, O king, these words,--They that are honest avoid deceit in play. Therefore, stop Duryodhana! Thou didst not, however, act according to my words. That is not strength which is opposed to softness. On the other hand, strength mixed with softness constitutes true policy which should ever be pursued. That prosperity which is dependent on crookedness alone is destined to be destroyed. That prosperity, however, which depends on both strength and softness, descends to sons and grandsons intact. Let, therefore, thy sons cherish the Pandavas, and the Pandavas also cherish thy sons.
