Pragâpati, indeed, is the year, and Agni is all objects of desire. This Pragâpati, the year, desired, 'May I build up for myself a body so as to contain Agni, all objects of desire.' He constructed a body one hundred and one-fold; and in constructing a body one hundred and one-fold, he built up for himself a body so as to contain Agni, all objects of desire, and himself became all objects of desire; there was not one object of desire outside of him: whence they say, 'The year (includes) all objects of desire;' for, indeed, outside the year there is no object of desire whatever.
