Mbh 12.139.12b

[417] Only he who has not felt any misery himself can say so in the midst of men. He, however, that has felt sorrow and misery, would never venture to say so. One that has felt the pangs of every kind of misery feels the misery of others as one's own. What I have done to thee, O king, and what thou has done to me, cannot be washed away by even a hundred years. After what we have done to each other, there cannot be a reconciliation. As often as thou wilt happen to think of thy son, thy animosity towards me will become fresh. If a person after avenging oneself of an injury, desires to make peace with the injured, the parties cannot be properly reunited even like the fragments of an earthen vessel. Men conversant with scriptures have laid it down that trust never produces happiness. Usanas himself sang two verses unto Prahlada in days of old. He who trusts the words, true or false, of a foe, meets with destruction like a seeker of honey, in a pit covered with dry grass.[418] Animosities are seen to survive the very death of enemies, for persons would speak of the previous quarrels of their deceased sires before their surviving children. Kings extinguish animosities by having recourse to conciliation but, when the opportunity comes, break their foes into pieces like earthen jars full of water dashed upon stone. If the king does injury to any one, he should never trust him again. By trusting a person who has been injured, one has to suffer great misery.'
