Please accept my blessings. I am in due receipt of your recent letter and I have noted the contents with pleasure. Your kind thoughts which you expressed are very nice and encouraging to me. Also you have asked some intelligent questions and I am answering them here.
You have asked how Krishna is with the spirit soul in the spiritual world and the answer is that Krishna is the heart of the spirit soul, or spiritual body, So Krishna is never apart from us. Either He remains in the heart of the material body, or He remains in the heart of the spiritual body. This is Krishna's Causeless Mercy to all of His beloved children, or living entities.
