While self-mastery is one of the biggest indicators of living a prosperous, happy life...
...not many people are willing to travel into the sometimes dark, murky corridors of one's OWN inner self.
Because, sometimes, it can be scary for us to find hidden skeletons in the closet that is our own subconscious mind. In other words, self-mastery requires the biggest sacrifices, and it's one thing that cannot be bought. It MUST be earned.
The only thing that can accelerate your path to Self Mastery is having an enlightened teacher by your side to guide you.
