This kind of teacher first makes sure you are in the right state of spirit (mind + body), so very often it starts with a purge.

The purge very often is so strong that the person has to take a second dose.

This purge brings things to mind. These things that surfaces the awareness are the things you are actually purging.

Many times what you need is to your body to assume a different shape that you are used to, and to change something that it's very rigid sometimes you need to break it.

Another thing that can be very relevant is that you are also purging the things that you do and you don't believe in.

You purge the things that you say and are not true.

After the purge you are ready to continue and flow through the experience.

Very cool article.
