"'"Pujani said, 'He whose feet have become sore, certainly meets with a fall if he seeks to move, move he may howsoever cautiously. A man who has got sore eyes, by opening them against the wind, finds them exceedingly pained by the wind. He who, without knowing his own strength, sets foot on a wicked path and persists in walking along it, soon loses his very life as the consequence. The man who, destitute of exertion, tills his land, disregarding the season of rain, never succeeds in obtaining a harvest. He who takes every day food that is nutritive, be it bitter or astringent or palatable or sweet, enjoys a long life. He, on the other hand, who disregards wholesome food and takes that which is injurious without an eye to consequences, soon meets with death. Destiny and exertion exist, depending upon each other. They that are of high souls achieve good and great feats, while eunuchs only pay court to Destiny. Be it harsh or mild, an act that is beneficial should be done. The unfortunate man of inaction, however, is always overwhelmed by all sorts of calamity. Therefore, abandoning everything else, one should put forth his energy. Indeed, disregarding everything, men should do what is productive of good to themselves. Knowledge, courage, cleverness, strength, and patience are said to be one's natural friends. They that are possessed of wisdom pass their lives in this world with the aid of these five. Houses, precious metals, land, wife, and friends,--these are said by the learned to be secondary sources of good. A man may obtain them everywhere. A person possessed of wisdom may be delighted everywhere. Such a man shines everywhere. He never inspires anybody with fear. If sought to be frightened, he never yields to fear himself. The wealth, however little, that is possessed at any time by an intelligent man is certain to increase. Such a man does every act with cleverness. In consequence of self-restraint, he succeeds in winning great fame.
