For a year Soma should be pressed,--the year is everything, and the one hundred and one-fold (altar) is everything: by means of everything he thus gains everything. Should he be unable (to press Soma) for a year, he should perform the Visvagit Atirâtra with all the Prishthas, and at that (sacrifice) he should give away all his property; for the Visvagit (all-conquering) Atirâtra with all the Prishthas means everything, and all one's property means everything, and the one hundred and one-fold (altar) means everything: by means of everything he thus gains everything.
