<p>The Book on the Living God, The Book on Life Beyond and this book form a trilogy. These three books should be read together. The Book on Human Nature presents basic concepts about human nature with the goal of inspiring readers to awaken the timeless, spiritual spark within. We become fully human only when the spiritual potential within us gradually awakens and infuses our material, purely animal selves. It is a path that every human being may and should pursue. A central understanding is that all life results from the joining of opposites, in particular, the polarity of male and female energies. Bô Yin Râ emphasizes that the true spiritual human being is male and female united in one entity; when we seek our spiritual self, we must call forth the male and female in ourselves and in all things. He discusses the biblical fall from grace as a descent from the spiritual plane, in which male and female were united, onto a material plane, in which male and female are split apart. Here on earth, this split can be healed within marriage. A true marriage, Bô Yin Râ tells us, is preparation for the life beyond: by coordinating the desires, wills and attitudes of two beings we once again bring about, in some measure, the original state in which male and female energies are united. </p><p><br></p><p>The Kober Press publishes the only English translations of the books of Bô Yin Râ authorized by the Kober Verlag, Switzerland.
