Mbh 5.35.6b

Do that during youth which may ensure a happy old age; and do that during thy whole life here which may enable thee to live happily hereafter. The wise prize that food which is easily digested, that wife whose youth hath passed away, that hero who is victorious and that ascetic whose efforts have been crowned with success. The gap that is sought to be filled by wealth acquired wrongfully, remaineth uncovered, while new ones appear in other places. The preceptor controlleth them whose souls are under their own control; the king controlleth persons that are wicked; while they that sin secretly have their controller in Yama, the son of Vivaswat. The greatness of Rishis, of rivers, of river-banks, of high-souled men, and the cause of woman’s wickedness, cannot be ascertained. O king, he that is devoted to the worship of the Brahmanas, he that giveth away, he that behaveth righteously towards his relatives, and the Kshatriya that behaveth nobly, rule the earth for ever. He that is possessed of bravery, he that is possessed of learning, and he that knows how to protect others,--these three are always able to gather flowers of gold from the earth. Of acts, those accomplished by intelligence are first; those accomplished by the arms, second; those by the thighs, and those by bearing weights upon the head, are the very worst. Reposing the care of thy kingdom on Duryodhana, on Sakuni, on foolish Dussasana, and on Karna, how canst thou hope for prosperity? Possessed of every virtue, the Pandavas, O bull of the Bharata race, depend on thee as their father. O, repose thou on them as on thy sons!’”
