Goodness that is costly!

What brings you to want to learn it?
What comes out of something like this? What is it's point and purpose for you to do this? What do people get out of this that is beneficial for them? Is there some way someone can work with past information to help serve them in their current situation - circumstance? If so...why and what for and how?

Sorry for all the questions.

Good luck in your quest to train for this
