This Universal Life penetrates all things. It has two aspects, a rising and a falling, an expansion and a contraction. Through the heating of expansion in Love the Higher was formed; through the cooling of contraction in Beauty the Lower or external was formed. The waves of vibrations from these met and intermingled forming the mind-mesh where light and darkness both are found. The Universal Light falling between the meshes of mind upon the outer sphere gave rise to the myriad of forms which have been given names by man to distinguish them, but really the Essence is one and the same. Who understands this understands something of the Nature of Allah.
