I'm not sure if anyone has heard of the Doshas which is a Hindu belief that we are all balances of three basic forces. Vata Pitta and Kapha.
The idea works on the premise that each dosha controls an aspect of the universe and how it creates and destroys and so forth. You can be the judge though.
Also, apparently each dosha has physical characteristics which can help in identifying what dosha you are or what dosha someone else is.
It is interesting how down to earth it all is. You don't have to be one dosha, you can be a mix of all doshas. But When you are born you have a basic balance which, if offset, leads to health problems.
Now I have always agreed with this sort of approach because it is more intuitively based. I just thought it might be interesting to post this because it shares alot of qualities with Socionics. Something tells me there might even be some influence.
