Often people ask me for more information or to recommend further reading on the chakra system. Recently I've been reading  the book Wheels of Life by Anodea Judith which was written over 20 years ago.  Her later book Eastern Body Western Mind is a great resource also and one I reference often in my practice. While the chakra system they reference is a bit different than the one I use in my Crystal Resonance Therapy Practice  I would highly recommend Wheels of Life as a thorough introduction to the chakra system. Both of these books are great!

I also just came across this podcast with Anodea Judith speaking on the chakra system.
