_Death_ is a centripetal withdrawal of the soul from the material Without to an Inner zone of Spiritual, or Potential, Being. And in due time, analogy assures us, having assimilated and transformed the resultant of a terrestrial existence into a new potential of Life, Life issues forth again, by the centrifugal impulse of re-Birth, to differentiate itself once more in living form upon the Outer plane. (_Re-incarnation_ is, obviously, the true interpretation of _Resurrection of the body_, which otherwise is scientifically impossible.) Winter withdrawal, or Involution, of the sap of Vegetation from the outer plane of functioning to the inner plane of potential Life, whereby it derives such new increment of Vital potential as, with the outgoing of sap again in the renaissance of spring, evolves in increased growth and new foliage, is further example of the principle and processes of Dominance and Recessiveness--of the female Vital impulse and the male Developmental impetus, operating in an eternal tidal rhythm of ebb and flow. XII _Dual planes of Mentality: Outer and Material, Inner and Occult_ As in the Domain of Life and vital processes, so in the Domain of Consciousness and nervous processes, there are two planes of function; an Inner and occulted plane of Mind, or potential Consciousness, and an Outer plane of material Consciousness; representing respectively afferent (or centripetal) and efferent (or outgoing) nervous currents. Faculty and sense may be regarded as having developed in one direction along lines of the telescope, with increasing capability to horizon the Without; while they have developed simultaneously along lines of the microscope, to reveal an Invisible Within. The Senses, which adapt man's Consciousness to environment by the functions of Sight, Hearing, Touch, Taste, Smell, have become, with evolutionary development, so increasingly sensitised in response to The Without as ever further to have set him in rapport with the world exterior. While, at the same time, so have they become sensitised in response to The Within, as ever further to have deepened and quickened his apprehension of an occulted Interior plane. Faculty has acquired thus, simultaneously with its increasing power of focusing the Outer and Objective, an increasing power so to invert its focus as to penetrate ever more deeply into the Inner and Subjective, alike of man's own constitution and that of environment. These two contrary, but co-operative, modes of mentality are, respectively, Intellection and Intuition--Male and Female modes of mind. XIII _Differentiation of the Zygote, or Mated Sex-cell_ I have described, throughout, the right side of the human body as the male-side--that in which the Male-traits of Humanity are specialised in the individual; the left as the woman-side, that in which the Woman-traits of Humanity are centred.
