The Chinese herbalists classified energy as three types – Jing, Qi and Shen.
I’ve replaced Qi with Mojo as that’s what most people know it as.
Jing is the Oil.
Mojo is the Fire.
Shen is the Heat & Light.
Let me write it another way.
OIL -> FIRE -> HEAT & LIGHT
JING -> MOJO -> SHEN & FEELINGS
I know you’re really tired after all the things you did and didn’t do at Christmas so I’ll get straight to it.
The ancient yogic practitioners – Indian or Chinese or whoever… they all agreed on this. That Jing is a primal energy we were born with, primal sexual energy as it were, the oil of our system. Once it gets drained the body ages quickly and dies. They all agreed on this and devoted a big part of practice to conserving sexual energy by preventing the loss of sexual fluids.
