lol, thanks for noticing the book, it is one of the most important books I have read in fact, the Dalai Lama excommunicated him in part for writing it. Though I don't think that means much because I have seen photos of them hanging out together after that.
It is a very technical book about something that is considered "secret" which the Tibetans don't have a word for, closest being "Oral tradition." So it never should have been written down at all, but to me its like a clean glass of fresh water.
the title is: Clear Light of Bliss.http://www.tharpa.com/us/book-Clear.Lig ... s-602.html
For one thing you can learn Tummo from these meditations which saves on the heating bill:
"The Tibetan term `tummo' means `Fierce One' and is generally used to refer to Heroines, who are slightly wrathful in appearance and who bestow spontaneous great bliss on their consorts, the Heroes. The red drop at the navel in the nature of fire is also called tummo because its function is similar to that of the fierce Heroines. In this text, however, it will be referred to simply as `inner fire'."
This is the root cluster for putting the snake ( red drop ) In the Egg Chair ( triple burner ) rather then around it which would be traditional in western Alchemy...
For example when you see a elite talking about "fire in the belly" its often a code for western initiation in this practice which can give one a lot of usable energy and really fuel a successful working life. In the west this tradition comes to us via the Greeks who got it from Egypt, Fire of ISIS.
Also the title is a pun on Luxrender
