Many people simply go through the motions, going from one workshop to the next because they do not sustain their own development and repeatedly need the group boost. This is not a particularly productive course of action.

There are other reasons for auditing a course, such as one that contains a great deal of information, particularly multi-dimensional information, since auditing it can allow deeper layers of meaning to be revealed. Another reason is to become more familiar with that class environment if the person auditing is a teacher-in-training.

As to what you should study, your best guidance for that will come from your own clear intuition. If you have not developed your intuition to where it speaks clearly enough, that is a good place to start learning.

Given your interest in Sacred Geometry, I suggest you have a look at Crystalline Consciousness Technique, which does use sacred geometry and is strongly focussed on each practitioner having their own connection to CCT. The site is www.crystallineconsciousness.com. It also would have provided a tool for you that could have eased the difficult class environment you describe in another post since it is particularly effective for group work.

I have enjoyed looking at your artwork as I am artist myself. Have a great journey on your learning adventures!
