The Secret of the Golden Flower: The Classic Chinese Book of Life

N.B.: Unlike the first Edition from Wilhelm and Jung who translated from a shortened English version and not from the original and complete Chinese one - what they probably could not know - this is a brilliant a new translation from a known scholar in this field.
From The Book's Introduction:The Secret of the Golden Flower is a lay manual of Buddhist and Taoist methods for clarifying the mind. A distillation of the inner psychoactive elements in ancient spiritual classics, it describes a natural way to mental freedom practiced in China for manycenturies. The golden flower symbolizes the quintessence of the paths of Buddhism and Taoism. Gold stands for light; the
light of the mind itself; the flower represents the blossoming, or opening up, of the light of the mind. Thus the expression is emblematic of the basic awakening of the real self and its hidden potential. In Taoist terms, the first goal of the Way is to restore the original God-given spirit and become a self-realized human being. In Buddhist terms, a realized human being is someone conscious of the original mind, or the real self, as it is in its spontaneous natural state, independent of environmental conditioning. This original spirit is also called the celestial mind, or the natural mind. A mode of awareness subtler and more direct than thought or imagination, it is central to the blossoming of the mind.
The Secret of the Golden Flower is devoted to the recovery and refinement of the original spirit. This manual contains a number of helpful meditation techniques, but its central method is deeper than a form of meditation. Using neither idea nor image, it is a process of
getting right to the root source of awareness itself. […]
