Thus has wisdom, more secret than secrecy itself, been declared unto thee by Me; having reflected over it fully, then act as thou wishest.

Thus I have declared to you knowledge more secret than all secrets. Reflect on it fully, and then do as you choose.

Krishna now steps back and leaves the decision to Arjuna. He has explained knowledge more secret than any secret. Arjuna should reflect on it fully and then act as he chooses. This is one of the most notable moments in the Gita: after all the teaching, Krishna does not command but invites free and thoughtful choice. The verse respects Arjuna's freedom and makes his final decision his own.
