Ornament of Stainless Light
An Exposition of the Kalachakra Tantra
— by Khedrup Norsang Gyatso
This is another one book from my Dharma Collection.
It contains the Kalachakra texts - an amazingly detailed theory of cosmology and astronomy, especially about the movements of the various celestial bodies.
Highly Recommended.
