16. But the Agnihotra and the rest, (because they tend) to that effect only; this being seen.
It might here be said that special works incumbent on the several âsramas, as e. g. the Agnihotra, need not be undertaken by those who are not desirous of their results, since these works also fall under the category of good works the result of which does not 'cling.'--This view the Sûtra sets aside. Such works as the Agnihotra must be performed, since there is no possibility of their results not clinging; for him who knows, those works have knowledge for their exclusive effect. This we learn from Scripture itself: 'Him Brâhmanas seek to know by the study of the Veda, by sacrifices, gifts, austerities, and fasting.' This passage shows that works such as the Agnihotra give rise to knowledge, and as knowledge in order to grow and become more perfect has to be practised day after day until death, the special duties of the âsrama also, which assist the rise of knowledge, have daily to be performed. Otherwise, those duties being omitted, the mind would lose its clearness and knowledge would not arise.--But if good works such as the Agnihotra only serve the purpose of giving rise to knowledge, and if good works previous to the rise of knowledge
perish, according to the texts 'Having dwelt there till their works are consumed' (Kh. Up. V, 10, 5) and 'having obtained the end of his deeds' (Bri. Up. IV, 4, 6), to what then applies the text 'His sons enter upon his inheritance, his friends upon his good works'?--This point is taken up by the next Sûtra.
