This extraordinary collection of teachings and commentaries illuminates the many profound mysteries of inner alchemy, one of the most important dimensions of the Taoist tradition. The science of inner alchemy consists of meditation practices that enable the individual to have a more intimate, energizing, and inspiring relationship with life. Although these techniques are described in the sourcebooks of ancient Taoism, they are often couched in cryptic symbolic language, making it difficult for today's seekers to put these teachings into practice. Some classical Taoist writers, however, did adopt a more explicit manner of expression. Practical Taoism is a collection of writings from these more accessible commentators on the traditional alchemical texts, compiled by a seventh-generation master of the Northern Branch of the Complete Reality School of Taoism known as the Preserver of Truth.
