I wanted to know if the primary centers are the main factor in OBE leaving out deep relaxation? Like are all the naturals who can easily OBE have higher developed primary centers thus making projection easier without as much preparation?

So instead of constantly trancing to train yourself to get into a relaxed state easily and quickly. You can do primary center work. Although The first way seems faster since you cant rush through primary center work.

In other words, if you want to be able to go to the park do an exit technique and OBE easily within a minute. Aside from constantly OBE to develop an ancor or reflex to it. You train the primary centers to have a higher level of minimum activity which makes simple OBE possible and quick?
