Explanation:

The Lord [1] said that God is also a knower like the soul. Here the word ‘also’ is very much stressed by repeating words i.e., ‘cha’ and ‘api’. Such repetition indicates that God is not the knower simply by the reason that God is the soul. The stress indicates that God is the knower not by the normal way of being the soul but that God is the knower in some special way. The normal logic is that the soul is the knower because the soul is awareness. The special logic must be that God is the knower even though He is not awareness. God is beyond awareness and so if God is the knower, the reason is not because God is awareness. The special reason is that since God is the source of everything in creation and can do anything, God can know anything without being awareness.
