sisṛkṣuḥ śiśirāṇyeṣa dakṣiṇāṃ bhajate diśam |

In the same way, that destroyer of darkness--the divine Sun--also moveth on this unobstructed path, animating the universe. When, desirous of causing dew, he repaireth to the south, then there ensueth winter to all creatures. Then the Sun, turning back from the south, by his rays draweth up the energy from all creatures both mobile and immobile. Thereupon, men become subject to perspiration, fatigue, drowsiness and lassitude; and living beings always feel disposed to slumber. Thence, returning through unknown regions, that divine effulgent one causeth shower, and thereby reviveth beings. And having, by the comfort caused by the shower, wind, and warmth, cherished the mobile and the immobile, the powerful Sun resumeth his former course. O Partha, ranging thus, the Sun unerringly turneth on the wheel of Time, influencing created things. His course is unceasing; he never resteth, O Pandava. Withdrawing the energy of all beings, he again rendereth it back. O Bharata, dividing time into day and night, and Kala, and Kashtha, that lord, the Sun, dealeth life and motion to all created things.'"
