Be careful of hidden knowledges. There are many of them, but unfortunately, many among them are planted falsely. So what appears to be "Wow! This is the Truth!" turns out to be yet another manipulation to distract our easily distracted emotional self. The training which takes a lifetime's discipline is to sort out Truth from its many glitzy impersonators. Just because something appears "hidden" doesn't mean it reflects reality; it may be "planted". That said, you are correct that reality is now mostly hidden under the obvious falsehoods that comprise the "orthodox" world we are bombarded with daily. Good luck and welcome!
