The entire ninth chapter distills into this one shloka. Four instructions, each beginning with 'mat' or 'mam' — the insistence is unmistakable. Fix your mind on me. Be devoted to me. Worship me. Bow before me. Do this, and you will come to me.
Krishna does not ask for perfection. He does not list prerequisites. He does not say you must first master all of yoga or memorize every scripture. He says: turn toward me. With your mind, with your heart, with your actions, with your humility. That is enough.
The word 'mat-parayanah' closes both the shloka and the chapter. It means: the one for whom I am the ultimate refuge. When a person's deepest orientation points toward the divine — not as an occasional thought but as the ground on which they stand — that person has understood the Rajavidya, the king of all knowledge.
