The man who is full of faith, who is devoted to it, and who has subdued the senses obtains (this) knowledge; and having obtained the knowledge he attains at once to the supreme peace.

One who has faith, who is devoted to it and has mastered the senses, gains knowledge; having gained knowledge, he soon attains supreme peace.

Krishna names three qualities that lead to knowledge: śraddhā, faith or trust; tatparatā, single-minded devotion to the goal; and control of the senses. With these, knowledge (jñāna) is gained, and with knowledge comes supreme peace, quickly. The verse links the inner attitude of trust with practical discipline. Faith here is not blind belief but a confident openness that allows one to persevere. The promise of peace answers the turmoil in which Arjuna began, offering a state beyond his present grief.
