BG 17.28

Anything done as sacrifice, charity or penance without faith in the Supreme, O son of Pṛthā, is impermanent. It is called asat and is useless both in this life and the next.

17.28. Without faith, whatever oblation is offered, what-ever gift is made, whatever austerity is practised, and whatever action is undertaken, that is called ASAT and it is of no avail after one's death and in this world.

17.28 Whatsoever is done without faith, whether it be sacrifice, austerity or gift or anything else, as called Asat' (meaning Unreal') for it is the negation of Sat,' O Arjuna! Such an act has no significance, here or hereafter."

17.28 Asradhaya etc. ASAT : not praiseworthy (or inauspicious). Therefore Happiness just easily arises for those who exert in the prasieworthy (or auspicious) act.

17.28 Offerings etc., when performed without faith, are Asat (i.e., unreal, bereft of efficiency), although they might be what has been enjoined by the Sastras. Why so? Because it is naught here or hereafter; it will not lead to release nor to any desirable result in Samsara.

17.28 O son of Prtha, whatever is hutam, offered in sacrifice, poured as oblation; and dattam, given in charity to Brahmanas,without faith; whatever tapah, austerity; is taptam, performed without faith; so also, whatever is krtam, done without faith, e.g. praise, salutation, etc.; all that ucyate, is said to be; asat iti, of no avail, since it is outside th course of discipline leading to Me. Ca, and, although involving great effort; na ca tat, it is of no conseence; pretya, after death, for producing (some) result; na, nor even for any result; iha, because it is condemned by the wise. [Thus it is established in this chapter that, among persons who are not at all versed in the scriptures, but are possessed of (either of the) three characterisitcs of sattva, (rajas) etc., only those shall attain to Liberation who steadfastly resort to sattva alone by partaking of sattvika food, (performing sattvika) sacrifices) etc. to te exclusion of rajasika and tamasika food etc., who destroy any defect that might arise in sacrifice etc. by uttering the names of Brahman, who have fully purified their intellect, and who have attained to the realization of Truth arising from one's being endowed with such disciplines as hearing and and thinking (sravana, manana) of, and meditation (nididhyasana) on Brahman.]

17.28 Whatever offering or gift is made, whatever austerity is practised and whatever action is performed without faith, that is called Asat, O Arjuna. It is naught here or hereafter.

17.28 O son of Prtha, whatever is offered in sacrifice and given in charity, as also whatever austerity is undertakne or whatever is done without, faith, is said to be of on avail. And it is of no conseence after death, nor here.
