For those whose minds are absorbed in me, O son of Pritha, I soon become the one who lifts them out of the ocean of mortal existence.
Explanation
Krishna is speaking to Arjuna about devotees who, as the previous verse says, give all their actions to him and meditate on him with single-minded yoga (discipline, spiritual practice). He promises that he himself will rescue them, before long, from the cycle of repeated birth and death (saṃsāra), pictured as an ocean. Devotional traditions stress his grace as the rescuer, while non-dual readings take the 'rescue' as the dawning of liberating knowledge.
