Humans are held to be the most complex lifeform on this planet. What does this mean I wonder? If you break something down into smaller and smaller pieces it becomes more and more simple, and human beings are no exception. As understanding grows, complexity dwindles.
Nature, which knows nothing other than cause and effect, finds complexity and simplicity meaningless.
Original mass
Q: Where did the original mass of the universe come from?
A: What is this "mass" you speak of? Where is the boundary between mass and not-mass? Both are manifestations of Mind. Mind is that which is without beginning.
