Chāndogya 7.21.1

यदा वै करोत्यथ निस्तिष्ठति नाकृत्वा निस्तिष्ठति कृत्वैव निस्तिष्ठति कृतिस्त्वेव विजिज्ञासितव्येति । कृतिं भगवो विजिज्ञास इति ॥ ७.२१.१ ॥

When one acts, then one stands firm; without acting one does not stand firm; having acted, one indeed stands firm. Action, indeed, is to be inquired into. Venerable sir, I wish to inquire into action.
