There are also sexual methods to consider, specifically in relation to Grant's understanding. He showcases a lot of different traditions which he believes carries the essence of the Typhonian tradition as he sees it. But probably one of the most effective contact with the Tunnels via the Atus would probably be through "erotocomatose lucidity". If you are not familiar, this method involves total sexual exhaustion to produce a state of "near death" which leads to a visionary state. This could be incorporated with various ritual techniques of one's choosing.
Grant points to other methods, with his own twist, and he insists repeatedly that none of these are homosexual in nature. Repeatedly.
However, he did point to Michael Bertrieaux's insistence that any sexual visualizations should be as violent and disgusting as possible, and by this is meant through monopolar activities if one reads MB without Grant's filter. The idea here being that beautiful images cause seductive allurements that lead the magician into obsession or whatever.
For interesting sex partners that can be related to the Tunnels of Set, you can look at 777 Column CLXXXIII, which Grant refers too I think, but I also think I saw another section somewhere with "vampiric sylphs". But anyway, as an example, for Atu XIII, Death, The Path of Nun, you can find creatures such Stryges, Lamias and Witches (as inhuman creatures, not practictioners) and develop visualizations from there. The next column over relates these to the intestines, so as to augment the horror-hentai imagination.
There are also methods of the Temple of Ascending Flame, which seemed kind of fun, particularly in regards to the "Cave of Lillith" - but I have only read one document that I recall. Still, the sigils are a bit more elegant than Crowley's, being somewhat vaginal in nature.
