1. Krsna sees everything

    Don't think that whatever you are doing, Krsna cannot see. In the Deity room, if you think that "This Deity is made of brass. Whatever nonsense I can do, He does not see," no, He can see everything. Angani yasya sakalendriya-vrttimanti pasyanti panti kalayanti [Bs. 5.32]. He sees. You rascal, you do not know how Krsna sees. You think that "He has these brass-made eyes. He cannot see. I can do all nonsense with…" No. That is not. He can see everything.

    So Krsna can see within our mind how much we are surrendered and how much we are after material enjoyment.
