The mandala is an archetypal image whose occurrence is attested throughout the ages. It signifies the wholeness of the Self.  This circular image represents the wholeness of the psychic ground or, to put it in mythic terms, the divinity incarnate in man.
-Carl Jung

It's easy to incorporate mandalas in your spiritual and energetic practice.

One way is to use the coloring book exercise as a way to focus and anchor your intentions into the physical. 

Choose a page which contains the images or themes that you reflect your intentions.
