In Taoism, there are various traditions and schools of thought that have come along through history. Taoist schools are rare and hard to find because there are so few of them out there and most of the secrets of Taoist Alchemy are guarded and kept secret. Why? Because in the old days, knowledge of these arts led to incredible power so warlords and Emperors would make sure these secrets didn’t get into their enemy’s hands. In the West, the Knight’s Templars came back from Jerusalem with a mighty secret (Alchemy) and rose to power almost overnight. No wonder why the Church and ruling establishment went after them and killed them? Those in power like to keep it that way 
The study of Taoist Alchemy is a tricky one. One must understand basic precepts of Taoism, Taoist tantric sex, Taoist yoga, and Qigong philosophy to have a foot in the door. Modern Taoist schools seldom teach all of this because most are either focused on scripture or on Qigong (Qi Gong) energy work alone. Qigong philosophy is important as is the practice but it is not everything. To understand Taoist Alchemy, we need to understand the underlying philosophy. We need to understand Who we really are in relation to this Universe and how things work here.
