12.26.9

kālena kṛṣṇāśca sitāśca rātryaḥ kālena candraḥ paripūrṇabimbaḥ |
nākālataḥ puṣpaphalaṃ nagānāṃ nākālavegāḥ sarito vahanti || 9 ||

"Vyasa said, 'No man can acquire anything by his own acts or by sacrifices and worship. No man can give anything to a fellow man. Man acquires everything through Time. The Supreme Ordainer has made the course of Time the means of acquisition. By mere intelligence or study of the scriptures, men, if Time be unfavourable, cannot acquire any earthly possession. Sometimes an ignorant fool may succeed in winning wealth. Time is the efficacious means for the accomplishment of all acts. During times of adversity, neither science, nor incantations, nor drugs, yield any fruits. In times, however, of prosperity, those very things, properly applied, become efficacious and bear success. By Time the winds blow violently: by Time the clouds become rain-charged; by Time tanks become adorned with lotuses of different kinds; by Time trees in the forest become decked with flowers. By Time nights become dark or lighted. By Time the Moon becomes full. If the Time for it does not come, trees do not bear flowers and fruits. If the Time for it does not come, the currents of rivers do not become fierce. Birds and snakes and deer and elephants and other animals never become excited when the Time for it does not come. If the Time for it does not come, women do not conceive. It is with Time that winter, and summer, and the rainy season come. If the Time for it does not come, no one is born and no one dies. If the Time does not come, the infant does not acquire power of speech.
