Bhagavad Gita Verse 17.28
अश्रद्धया हुतं दत्तं तपस्तप्तं कृतं च यत्।असदित्युच्यते पार्थ न च तत्प्रेत्य नो इह।।17.28।।
aśhraddhayā hutaṁ dattaṁ tapas taptaṁ kṛitaṁ cha yat asad ity uchyate pārtha na cha tat pretya no iha
हे अर्जुन ! बिना श्रद्बा जे के किया हुआ हवन, दिया हुआ दान एवं तपा हुआ तप और जो कुछ भी किया हुआ शुभ कर्म है —– वह समस्त ‘असत्’ —– इस प्रकार कहा जाता है ; इसलिये वह न तो इस लोक में लाभदायक है और न मरने के बाद ही |
If any of these acts, O Arjuna, whether it is Spiritual Sacrifice, Self-perfection or the offering of pure and pleasant gifts, is done without faith and good incentives, Asat (all that is untrue and representative of darkness) is attained. By achieving Asat, one has really gained absolutely nothing, O Son of Kunti, because I hold the acts performed in Asat as useless, and having no importance in this world or in the afterworld.
