I have a question concerning an alleged quote in the Candamaharosana about, well, a ritualized threesome, which appears in the book "Sexual Secrets: Alchemy of Ecstasy" by Nik Douglas & Penny Slinger.
One woman, coming from the disc of the moon, is enjoyed by another similar one. The third person is different from these two and should balance their forces. By enjoying together, they all become free from decay and death. The right and the left blend together in the Central Pathway. He stimulates both; they arouse each other and combine with him. The two moons are always filled with nectar; the sun is ever burning.
I have Christopher Starr George's translation (which is cited in the bibliography of the above book), but I cannot find this passage or anything remotely similar. It's possible that I am [repeatedly] missing it, or that the author in question - Nik Douglas, may have distorted the meaning to fit an agenda or even outright fabricated. Naturally, one would prefer this not to be the case, yet sadly it seems common as the spiritual supermarket converges on sexual lifestyle accessories.
So my question, in a nutshell is, does this actually refer to anything in the Candamaharosana, and more broadly, are there any practices which involve more than 2 participants in a such a manner?
