The Ultimate Realm is a timeless written treasure, completed during the 1940's by Han-ching Lao-jen [the Venerable Vessel of Stillness] on the cloud-hidden heights of China's sacred Western Peak-Hua Mountain, inheriting the essence of China's traditional culture and joining it with principles of natural and social science. This book draws judiciously on religious philosophy, both Chinese and foreign; it was produced by constant pure-hearted communion with the non-physical, spirit realm.
