There is a presence within you that is not made of flesh and does not die when the body dies. It is the life animating your form, the awareness looking out through your eyes, the formless consciousness that gives rise to all living things. It dwells in you now.
When you turn attention inward and feel the subtle aliveness in your hands, your chest, your whole body, you sense that presence directly. The body ceases to be merely a physical object and becomes filled with life, quickened from within. This does not wait for after death; it happens the moment awareness inhabits the body you are living in.
