Advanced Yoga Practices: Easy Lessons for Ecstatic Living

This is a wonderful book that answers tons of questions about the practice of yoga and spiritual development.
The author prefers to remain anonymous and calls himself Yogani. The beauty about this writer is that he takes the mystery out of a lot of questions that arise when you are a serious yogi, giving answers in plain English, and dispensing with a lot of the evasiveness that I find a lot of teachers "specialize" in.

The book is so popular that there are AYP internet forums where yogis chat about their yoga experiences. You can also read parts of the book online.

It is such a extensive resource and we have the brilliant Yogani to thank for it.

The AYP book is a hefty volume, and is available in paperback at Amazon.com or at your local New Age-y bookstore. Yogani has also written some other books on meditation, Kundalini etc...

JAI Yogani !!
