AM.29 {u} _ Sunday _[April 21, 1918 e.v.] 9.20 [a.m.] Arcteon was ill during the night. Achita slept and Therion had the following vision which he dictated to Arcteon at 9.20. Critical glyphs, I saw how these are arranged. When any idea arises it is recorded automatically in every department of the mind. Each department im mediately sends in a report as to how it is effected by the idea, but of course only those reports which are loud make themselves heard in the consciousness. I got a clear idea of the spider's web structure of the mind. The _ahamkara_ appeared to me like a crystal, four hexagonal columns joined to the base (maybe octagonal, am not sure). And brought to a blunt point, each point occupying one of the angles of a tetrahedron which may explain the pyramid-phallus symbol. This glowed more or less brightly as each idea was recorded, rather like a tell-tale electric-light which registers a current passing thru a machine and gauges it. This crystal bulged or shrank to a certain extent from time to time but never lost the tetrahedral form. The colour of the light was that peculiar gold which jewellers call a rose finish. I am now reminded of the jewel of Mara. This glow is very closely connected with pleasure and pain. I got away from this by understanding it as a mere ganglion or node of the web and did several mystic stunts.
