Bhagavad Gita · 12.11

अथैतदप्यशक्तोऽसि कर्तुं मद्योगमाश्रितः।सर्वकर्मफलत्यागं ततः कुरु यतात्मवान्॥

athaitad apy aśhakto 'si kartuṁ mad-yogam āśhritaḥ sarva-karma-phala-tyāgaṁ tataḥ kuru yatātmavān

If you are unable to do even this, then take refuge in my yoga and renounce the fruits of all actions, being self-controlled.
