'The Rishi Bharadvâga,'--the Rishi Bharadvâga, doubtless, is the mind;--'vâga' means 'food,' and he who possesses a mind, possesses (bharati) food, 'vâga;' therefore the Rishi Bharadvâga is the mind.--'By thee, taken by Pragâpati,'--that is, 'by thee, created by Pragâpati;'--'I take the mind for my descendants!'--therewith he introduced the mind from the right side. Separately he lays down (these ten bricks): what separate desires there are in the mind, those he thereby lays into it. Only once he settles them: he thereby makes it one mind; but were he to settle them each separately, he assuredly would cut asunder the mind. This brick is threefold: the meaning of this has been explained.
