You can be in paradise only when you do not know what it is like to be in paradise. As soon as you know, paradise is gone. No effort of thought can take you back, for thought – the conscious awareness of yourself as a mortal being – is the Fall. In the Garden of Eden, the primordial human pair are clothed in ignorance of themselves. When they come to self-awareness, they find they are naked. Thinking of yourself is the gift of the serpent that cannot be returned.
