Saying Suvas, he enters Aditya (sun); saying Mahas, he enters Brahman. He there obtains lordship, he reaches the lord of the mind. He becomes lord of speech, lord of sight, lord of hearing, lord of knowledge. Nay, more than this. There is the Brahman whose body is ether, whose nature is true, rejoicing in the senses (prana), delighted in the mind, perfect in peace, and immortal. Worship thus, O Prakinayogya!
In plain words: Saying Suvas, the knower enters the sun, and saying Mahas, he enters Brahman, the ultimate reality. There he becomes master of his own mind, speech, sight, hearing and understanding. He reaches Brahman, which is like open space, true, joyful in life and mind, perfectly peaceful and undying. The teacher tells his student Prachinayogya to meditate on Brahman this way.
