The Mystery is revealed
This is a moment of supreme initiation when you finally get to see the real secrets.
This moment comes as a surprise because the knowledge that you are given is usually readily available to those whose diligence and patience has brought them to this very point of understanding.
I mention this because there is no course of study which can enlighten you like the inner voice can. This one piece of knowledge is the basis of every secret that has ever been told. The reason why these mystery schools cannot give you this answer beforehand is simple. If you knew then you wouldn't have to study you would only have to apply this one principle that the inner voice is your teacher and no one else.
