The body cannot know. And while you limit your awareness to its tiny senses, you will not see the grandeur that surrounds you. God cannot come into a body, nor can you join Him there. Limits on love will always seem to shut Him out, and keep you apart from Him. The body is a tiny fence around a little part of a glorious and complete idea. It draws a circle, infinitely small, around a very little segment of Heaven, splintered from the whole, proclaiming that within it is your kingdom, where God can enter not...
Like to the sun and ocean your Self continues, unmindful that this tiny part regards itself as you. It is not missing; it could not exist if it were separate, nor would the whole be whole without it. It is not a separate kingdom, ruled by an idea of separation from the rest. Nor does a fence surround it, preventing it from joining with the rest, and keeping it apart from its Creator. This little aspect is no different from the whole, being continuous with it and at one with it. It leads no separate life, because its life is the oneness in which its being was created.
