398. Because, then, love and wisdom, and thence will and understanding, are what are spoken of as the soul, it is to be shown in what follows how the soul acts upon the body and effects all its operations, and since this may be known from the correspondence of the heart with the will, and of the lungs with the understanding, by that correspondence the following propositions have been revealed:
(i) Love or the will is man's very life. (ii) Love or the will strives continually towards the human form and all things thereof (iii) Love or the will can do nothing through its human form except by marriage with wisdom or the understanding. (iv) Love or the will prepares a home or bed-chamber for its future wife, which is wisdom or the understanding. (v) Love or the will also prepares all the things in its own human form so that it may act together with wisdom or the understanding. (vi) After the nuptials, the first conjunction comes through the affection of knowing, from which springs an affection for truth. (vii) The second conjunction comes through an affection for understanding, from which springs perception of truth. (viii) The third conjunction comes through an affection for seeing truth, from which springs thought. (ix) Love or the will comes into sensitive and active life through these three conjunctions. (x) Love or the will introduces wisdom or the understanding into all things of its house. (xi) Love or the will does nothing except in union with wisdom or the understanding. (xii) Love or the will conjoins itself to wisdom or the understanding, and causes wisdom or the understanding to be conjoined to it. (xiii) Wisdom or the understanding, from power given it by love or the will, can be elevated and can receive such things as are of light out of heaven and perceive them. (xiv) Love or the will can be elevated in like manner and can perceive such things as are of heat out of heaven, provided it loves wisdom its partner in that degree. (xv) Otherwise love or the will draws wisdom or the understanding back from its elevation so that it may act in unison with itself. (xvi) Love or the will is purified by wisdom in the understanding if they are elevated together. (xvii) Love or the will is defiled in and by the understanding, if they are not elevated together. (xviii) Love, when purified by wisdom in the understanding, becomes spiritual and celestial. (xix) Love, defiled in and by the understanding, becomes natural and sensual. (xx) The faculty of understanding, called rationality, and the faculty of acting, called freedom, still remain. (xxi) Spiritual and celestial love is love towards the neighbour and to the Lord; and natural and sensual love is love of the world and of self (xxii) It is the same with charity and faith and their union as with will and understanding and their union.
