(online book) Qabalah: The Mystical Heritage of the Children of Abraham

I have read many books on the Qabalah. This is by far one of the best! 

Description: 

The book effectively presents the teachings of an accomplished and knowledgeable mystic, now retired from the world. He transmitted information and meditation methods in private meetings during the 1970s and 1980s.
He anonymously published a number of the first English translations of primary qabalistic texts,and distributed tens of thousands of copies through the Work of the Chariot Trust. This book is the first time that a senior student of the Work of the Chariot has compiled much of the teachings from those meetings on the core principles and practices of the Mystical Qabalah.

From the Author

The teachings in this book were transmitted in private meetings in the 1970's and '80's by the Work of the Chariot Trust. They are notable for their clarity, depth, and extensive interfaith considerations. I am the first senior student of this group to record its teachings.
