Preview of English translation:

20. And having taken up the two fires within his own self, and worshipped the sun with the Uttara-Narayana (litany, viz. Vajasaneyi Samhita XXXI, 17-22), let him betake himself to the forest without looking round; and that (place), indeed, is apart from men. But should he wish to live in the village, let him take up again the two fires in the churning-sticks, and having worshipped the sun with the Uttara-Narayana (litany) let him dwell at his home, and let him offer such sacrifices as he may be able to afford. But, indeed, this (sacrifice) is not to be imparted to any and every one, lest one should impart everything to any and every one, for the Purushamedha is everything; but one may only impart it to one who is known to him, and who is versed in sacred writ, and who may be dear to him, but not to any and every one.
