3. The Maruts, the Jagatī meter, the Saptadaśa hymn, the Vairūpa chant, the rainy season, the Apāna breath, the planet Venus, the Āditya gods, issue forth to the west. They shine, they rain, they praise, they enter again within and peer through an opening.

That is tranquil, soundless, fearless, sorrowless, blissful, satisfied, steadfast, immovable, immortal, enduring, named Vishṇu (the Pervader), the ultimate abode.
