There is an old story that after Creation, God was wondering where to hide the ultimate secrets of the universe. The Almighty contemplated: Should I hide them deep in the oceans? No; humans can invent submarines and these secrets can fall into unworthy hands. Should I hide them in the remote corners of the universe? Not good either; humans can develop spaceships and the secrets can get into wrong hands. Then an idea occurred to God: The secrets of the universe can be hidden at the bottom of humans' minds, deep in their souls. Then, only the worthy can find them.
