Always keeping himself absorbed in this way, the yogi whose mind is disciplined attains peace, which culminates in nirvana and rests in me.
Explanation
Krishna concludes his description of meditation practice to Arjuna by naming its fruit. The yogi, one who practises yoga (spiritual discipline), keeps the mind restrained and steady, and so reaches peace (śānti) whose highest point is nirvāṇa, the cessation of bondage and suffering. The phrase "rests in me" is read by devotional traditions as peace found in God, and by non-dualist readings as peace in one's own true self.
