I saw bits and pieces of Campbell as well, in PBS. I would venture that if the erotic carvings came up at all, would be in the context of uncoiling the kundalini, Astanga yoga, the Brahman...nirvana, you know the drill....but I wonder whether he'd really talk about nirvana through orgasm....as I have heard the tantrics and some yogis allegedly reaching higher state through the acts of coitus, well higher state not nirvana then. Make you wonder where they got willing partners though, thus tales of drug laced prasads, hypnotic eyes, and the dark dark tinge of tantra. There have been rumors though, that the first culture was tantric, and then came the Vedics (mantric) and through propoganda, managed to make tantra dark. I hardly know, who does? Bizzarre though that sex is so repressed in Nepalese culture, and on the other hand you see carvings like these and then the Kamasutra and as if that didn't confound you enough, Vatsyayana (who wrote kamasutra) was allegedly a bachelor and a celibate (in a way though, that explains some of the most outlandish positions he/she contrived) Weird still there comes rock and roll, then larry flint, then the huge porn industry and then the likes of Campbell to infuse it all with a dose of easter mysticism. While we, supposedly sitting on the motherlode of meanings and symbolism hee and haw and spoof it off, or feel confounded. There was Rajneesh I guess, but he only gave a thinly veiled excuse to orgy didn't he? Meanwhile, I flick on the tv and from soda, chewing gum, cars to trojan, sex is selling all. I suppose Hush, maybe you have it down, naked people grasp attention, so these temple carvings sold religion. Priests and statesmen.... bring in the artisans. Need reasons to make people throng to temples, let's have some visual aid. and you know what happens, once you give people religion, Marx, was it? who said it is the opiate of the masses? Priests and statesmen in cahoots. Just a fanciful thought, there is no way you could summarize a cultural phenomenon that big, in few sentences and cheap conspiratorial notes.
