Bhagavad Gita Verse 18.5

यज्ञ, दान और तप रूप कर्म त्याग करने के योग्य नहीं है, बल्कि वह तो अवश्य कर्तव्य है ; क्योंकि यज्ञ, दान और तप —-ये तीनों ही कर्म बुद्भिमान् पुरुषों को पवित्र करने वाले हैं ।

Tasks which involve works of sacrifice, gift-giving, and self-improvement should never be abandoned and should always be performed. I consider these acts, O Arjuna, to be those of purification and all those who are wise realize this fact.
