It’s position is an inch and a half below the navel, deep in the body, about 5 centimeters.

Hole (in a chakra)
Literally when a chakra doesn’t get the food it needs, there is a hole in the chakra, it’s empty. But because for whatever reason, the chakra remains empty, and we call that a hole. And a hole is crying to be filled, and now you might be 40 years old, and you are still trying to get that hole filled. So I would say that pretty much every human being, in Western society, except for a few have big holes in their second chakra: you weren’t fed what you needed.
