831. Those spirits are above the head, rather high, not directly above the head, but a little, though very little, towards the front. They are good spirits. They also spoke with me quite pleasantly, for they act and speak by a very pleasant flow. They said that they continually aspire to enter heaven, not knowing that they have been in heaven and were removed therefrom, in order that they might again be better perfected. Thus when the heterogeneous parts have been cast out from them they return again into heaven, exactly as is the case with the serosity in the ventricles, of which a part, as being the part that is cast off, is absorbed by the choroid plexus, a part transpires elsewhere, a part passes into the third ventricle beneath the pineal gland, and thus through the infundibulum toward the pituitary gland, where it is separated in a three-fold manner, and the parts are afterwards carried by various passages, channels and sinuses towards the jugular vein, so that they may be at hand to meet the chyle coming up through the thoracic duct. There the two are consociated and carried toward the heart, thence into the lungs, and so back again into the left ventricle [of the heart], and so on; part is carried towards the head through the carotid arteries; part goes downward towards all the viscera of the body. All of this is to the end that the purer blood or animal spirit may be formed, and thus the red blood; namely, that material things united with spiritual things may effectuate their living a unanimous life. 1748, Feb. 18.
