Yagnavalkya said: 'Let us hear what anybody may have told you.' Ganaka Vaideha replied: 'Satyakama Gabala told me that mind (manas) is Brahman.' Yagnavalkya said: 'As one who had (the benefit of a good) father, mother, and teacher might tell, so did Satyakama Gabala tell you that mind is Brahman; for what is the use of a person without mind? But did he tell you the body and the resting-place of that Brahman?' Ganaka Vaideha said: 'He did not tell me.' Yagnavalkya said: 'Your Majesty, this (Brahman) stands on one leg only.' Ganaka Vaideha said: 'Then tell me, Yagnavalkya.' Yagnavalkya said: 'Mind itself is its body, ether its place, and we should worship it as bliss.' Ganaka Vaideha said: 'What is the nature of bliss?' Yagnavalkya replied: 'Your Majesty, mind itself; for with the mind does a man desire a woman, and a like son is born of her, and he is bliss. Mind indeed, O King, is the Highest Brahman. Mind does not desert him who worships that (Brahman) with such knowledge, all creatures approach him, and having become a god, he goes to the gods.' Ganaka Vaideha said: 'I shall give you (for this) a thousand cows with a bull as big as an elephant.' Yagnavalkya said: 'My father was of opinion that one should not accept a reward without having fully instructed a pupil.'
In plain words: Janaka says Satyakama Jabala told him the mind is Brahman. Yagnavalkya says the mind is its body and space its home, and it should be honored as joy. Through the mind a man desires a wife, and the son born to them is a joy. He refuses payment until the teaching is complete.
