The emphasis shifts from the meaning of Tvam (you) to the meaning of Tat (that). Lord Krishna reveals the nature of Para and Apara Prakriti (Higher and lower manifestations of the Lord) and the means we can use to know the Lord. We come to understand the Lord as both the material cause and the efficient cause of creation.
