I see you are asking for statistics eh? This aint bodybuilding...calculating your muscle gains. This is about finding the right focus..how much time you invest in it is up to yourself...(5 minuts is a little short though I think)
some days ago i come to the following conclusion : is it possible that developing psychic abilities with training takes MORE OR LESS the same time than getting the brain used to a habit ? I mean, when a person wants to do a daily reality check they say that takes a few weeks to get the brain used and to become a habit also inside dreams, so with psychic abilities is more or less the same thing, i mean, getting the brain or subconcious used to working with psychic abitities instead of only using the five senses ? I hope this is true because THIS would finally be some kind of garantee that definetly i could have psychic abilities by continuos training, and be a big motivation for me.
One last question : does several 5 minutes session of concentration or psychokinesis each day is as effective as having two or three 20 minutes session or not ? I mean which of those methods makes less time to develop psychic abilities and concentration ?
