Mbh 12.310.2c

Destitute of tranquillity, seek thou to be tranquil, and bereft of wisdom as thou art, do thou seek to act wisely! He who moves in the companionship of the righteous succeeds, by his own energy, in acquiring the means of accomplishing what is beneficial for him both in this and the next world. Verily, the root of the benefit (which thus becomes his here and hereafter) is unwavering firmness. The royal sage Mahabhisha, through want of this firmness, fell from heaven. Yayati, also, though his merits had become exhausted (in consequence of his boastfulness and thought was hurled down from heaven) succeeded in regaining regions of felicity through his firmness. Thou art sure to attain to great intelligence, as also to what is for thy highest good, by paying court to virtuous and learned persons possessed of ascetic merit.'"
