Bhagavad Gita 12.11 — Letting go of results
अथैतदप्यशक्तोऽसि कर्तुं मद्योगमाश्रितः। सर्वकर्मफलत्यागं ततः कुरु यतात्मवान् ॥
athaitadapyaśakto'si kartuṃ madyogamāśritaḥ | sarvakarmaphalatyāgaṃ tataḥ kuru yatātmavān ||
Meaning
If you cannot do even this, then take refuge in me, control yourself, and give up the fruits of all your actions.
