The English words “secret” and “mystery” refer to knowledge that is “hidden”, and that needs to be discovered.
When dealing with the spiritual world, as opposed to simply the physical world, the method of discovering these “mysteries” or “hidden knowledge” is often referred to as “illuminating”.
It is like entering a dark room where one’s physical eyes cannot see what is in that room due to the darkness, so a light must be turned on in order to see everything clearly.
