अश्रद्धया हुतं दत्तं तपस्तप्तं कृतं च यत्।असदित्युच्यते पार्थ न च तत्प्रेत्य नो इह
aśhraddhayā hutaṁ dattaṁ tapas taptaṁ kṛitaṁ cha yat asad ity uchyate pārtha na cha tat pretya no iha
Whatever is done without faith, whether it be sacrifice, austerity, gift, or anything else, is called Asat (meaning "Unreal"), for it is the negation of Sat, O Arjuna! Such an act has no significance, here or hereafter.
Translated by Shri Purohit Swami
Whatever is sacrificed, given, or performed, and whatever austerity is practiced without faith, it is called 'Asat', O Arjuna; it is of no value here or hereafter (after death).
Translated by Swami Sivananda
