17. And of him who is chaste; for in Scripture (this is declared).
The knowledge of Brahman belongs to those who have to observe chastity, and men living in that state have not to perform the Agnihotra, the Darsapûrnamâsa, and similar works. For this reason also knowledge cannot be subsidiary to works.--But, it may be objected, there is no such condition of life; for texts such as 'he is to perform the Agnihotra as long as he lives,' declare men to be obliged to perform sacrifices and the like up to the end of their lives, and Smriti texts contradicting Scripture have no authority.--To meet this the Sûtra adds 'for in Scripture.' The three stages of life are recognised in Scripture only; cp. texts such as 'Those who in the forest practise penance and faith' (Kh. Up. V, 10, 1); 'Wishing for that
world only mendicants wander forth from their homes' (Bri. Up. IV, 4, 22). The text as to the lifelong obligatoriness of the Agnihotra is valid for those only who do not retire from worldly life.
