Talk:Sidereal plexus/@comment-203.51.6.201-20201008120342

It's worth noting that the solar plexus is an area of the body located just below the sternum, and "Sidereal" is to stars as "Solar" is to sun (and "Lunar" is to moon). The solar plexus is also the location of the third chakra.

I have no idea what the chakra stuff might be about, but I'd always assumed it was a play on the solar plexus.
