daivatebhyo namaskṛtya yastvarthānsamyagīhate |
dakṣo dākṣiṇyasaṃpanno na sa moghaṃ vihanyate || 20 ||

Efforts become unproductive of fruits in consequence of these two reasons: destiny without exertion and exertion without destiny. Without exertion, no act in this world becomes successful. Devoted to action and endued with skill, that person, however, who, having bowed down to the gods, seeks, the accomplishment of his objects, is never lost. The same is the case with one who, desirous of success, properly waits upon the aged, asks of them what is for his good, and obeys their beneficial counsels. Men approved by the old should always be solicited for counsel while one has recourse to exertion. These men are the infallible root of means, and success is dependent on means. He who applies his efforts after listening to the words of the old, soon reaps abundant fruits from those efforts. That man who, without reverence and respect for others (capable of giving him good counsel), seeks the accomplishment of his purposes, moved by passion, anger, fear, and avarice, soon loses his prosperity.
