Mbh 12.292.1c

[1516] That man who, reflecting with his mind, O king, and ascertaining his own ability, accomplishes righteous acts, certainly obtains what is for his benefit. Water poured into an unbaked vessel gradually becomes less and finally escapes altogether. If kept, however, in a baked vessel, it remains without its quantity being diminished. After the same manner, acts done without reflection with the aid of the understanding do not become beneficial; while acts done with judgment remain with undiminished excellence and yield happiness as their result. If into a vessel containing water other water be poured, the water that was originally there increases in quantity; even so all acts done with judgment, be they equitable or otherwise, only add to one's stock of righteousness. A king should subjugate his foes and all who seek to assert their superiority, and he should properly rule and protect his subjects. One should ignite one's sacred fires and pour libations on them in diverse sacrifices, and retiring in the woods into either one's middle or old age, should live there (practising the duties of the two last modes of life). Endued with self-restraint, and possessed of righteous behaviour, one should look upon all creatures as on one's own self. One should again reverence one's superiors. By the practice of truth and of good conduct, O king, one is sure to obtain happiness.'"'"
