I'm the anon who's still irritated at "SiriusAnon" for not saying what he means. So I read some (rather unpleasant) websites purporting to explain the significance of Sirius (and the Pleiades) to ancient cultures, freemasons, Aleister Crowley, theosophy, and the New Age.

Can I try to net it out? Feel free to disagree; I know you do.

To these groups, the bright star Sirius represents occult power or occult knowledge: "the sun behind the sun".

None of the websites I read mentioned other things that SiriusAnon seems fond of posting such as his numerical/geometrical symbolism of 6:5 which he related to the chemical structure of some molecule (was it adrenochrome? was it DMT?): a 6-carbon benzene ring attached to a 5-carbon ring.

I guess perhaps he relates all of that to some kind of chemical or mystical enlightment which he does not want to state explicitly.

I still didn't get anything useful out of the dig.
