There is nothing to remember.  It is all right there.  What you need to know will come to you when you surrender.  Cease trying.  You cannot force a memory or a fact to come to the surface.  It is given to you when you set the intention.  “How do I … What do I … What was the …?”  The answers to all such questions exist in the collective consciousness of the One Mind.  To access that Mind, which has a limitless storage capacity far greater than a limited brain, simply set the intention of tapping into that Mind of which you are a part.  With trust that what you need will be given to you, again we say, cease trying to remember and surrender.  The answer will come to you on a silver platter with divine timing.
