The Secret of the Golden Flower, by Wang Chongyang (full audio)

"The Secret of the Golden Flower" promises eternal life (end of the rebirth cycle, union with the Tao) to those of sound constitution. More pragmatically, it serves as a meditation guide, addressing posture, breathing, and contemplation, also providing cautions and confirmations. Written by Wang Chongyang, translated by Richard Wilhelm. *Carl Jung was influenced by this book, and references it in some of his works.
