17.23 "Om Tat Sat": This has been declared to be the triple designation of Brahman. By that were created formerly, the Brahmanas, the Vedas and the sacrifices.
17.24 Therefore, with the utterance of "Om" are the acts of sacrifice, gift and austerity as enjoined in the scriptures, always begun by the students of Brahman.
17.25 Uttering ï1Tatï1, without aiming at the fruits, are the acts of sacrifice and austerity and the various acts of gifts performed by the seekers of liberation.
17.26 The word ï1Satï1 is used in the sense of reality and of goodness; and so also, O Arjuna, the word ï1Satï1 is used in the sense of an auspicious act.
सद्भावे साधुभावे च सदित्येतत्प्रयुज्यते |
प्रशस्ते कर्मणि तथा सच्छब्दः पार्थ युज्यते ||१७-२६||
17.27 Steadfastness in sacrifice, austerity and gift, is also called 'Sat' and also action in connection with these (or for the sake of the Supreme) is called 'Sat'.
17.28 Whatever is sacrificed, given or performed, and whatever austerity is practised without faith, it is called 'Asat', O Arjuna; it is naught here or hereafter (after death).
अश्रद्धया हुतं दत्तं तपस्तप्तं कृतं च यत् |
असदित्युच्यते पार्थ न च तत्प्रेत्य नो इह ||१७-२८||
