Chapter VI. The Internal and the External Mind.THE mind is here drawn in two planes-the internal or spiritual mind B and the external or natural mind C.
The spiritual body D though separately drawn, is yet closely conjoined with the external mind, and in the Writings is generally inclosed in it.
The internal mind is the primary and special abode of love to the LORD and of love to the neighbor. The external mind is the abode of self-love and of love of the world. (DLW 396; DP 324; TCR 401, 402; AC 9701-9709; NJHD 36-53.)
Divisions of the degrees into internal and external other than this occur in the Writings, and the same degrees are differently designated in different passages. A certain degree may in one passage be called the internal man, in another the spiritual man, in another the inmost man, in another the middle man, in another the rational man, and yet in others classed with and called the exterior or external man; all arising from different points of view.
In this diagram the internal mind B in the individual man or angel answers to the plane of the angelic heavens, and the external C answers to the region of the world of spirits.
In Apocalypse Explained, AE we read, -
In Apocalypse Explained, AE 940, this natural C is called natural internal in distinction to an extreme degree of the natural mind close to the body, which constitutes a natural external not here drawn, but to be drawn in Diagram XI
In the original Latin the internal mind is frequently called Mens, and the external mind and spiritual body together are called Animus, though Animus is sometimes restricted to the natural mind merely. In a wider sense Animus includes also that part of the external mind formed of natural substances as mentioned in Divine Love and Wisdom, 257. (See Diagram XV.)
In the prayer "Thy will be done as in heaven so upon the earth", "as in heaven" means "as in the spiritual mind" and "so upon the earth" means "so in the natural mind." "That your days and the days of your sons may be multiplied as the days of the heavens upon the earth," (Deut. xi, 21), means that with the regenerate the states of the natural mind will accord with the states of the spiritual mind.
