Now Âditya, the sun, when he rises, goes toward the East, and thus receives the Eastern spirits into his rays. And when he illuminates the South, the West, the North, the Zenith, the Nadir, the intermediate quarters, and everything, he thus receives all spirits into his rays.

In plain words: When the sun rises and shines on the east, it gathers the living beings there into its rays. As it lights up every direction, above and below, it takes in all living beings.
