śharaṇam

दूरेण ह्यवरं कर्म बुद्धियोगाद्धनञ्जय

śharaṇam — refuge

Action for the sake of its fruit is far inferior, Arjuna, to action guided by understanding. Take refuge in understanding. Those who work only for the fruit are wretched.

गतिर्भर्ता प्रभुः साक्षी निवासः शरणं सुहृत्

śharaṇam — shelter

I am the goal, the upholder, the lord, the witness, the dwelling, the refuge, the friend; the origin, the dissolution, the ground, the resting place, and the imperishable seed.

सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज

śharaṇam — take refuge

Let go of every duty and take refuge in me alone. I will free you from all wrongdoing. Do not grieve.
