I don't believe any of that! What I do know is that some of the aforementioned people (those who aren't charlatans), have been able to use their perceptions at a heightened level. We all have the same abilities (yes...they can be altered by illness, drugs or genetic anomalies), however...we've "learned" how not to use many of them or have become "dumbed down" away from understanding our own capabilities.
Telepathy, separation of self, intuitive thought, cognition, energy transference, aren't the things of "special beings," they're part of all of us. It makes me laugh, while at the same time feel sad, when I hear people say that they went to a lecture and this man or that woman was so spiritual...without realizing that they themselves are too. Actually - I think the word "spiritual" has been overused, and has lost it's meaning. It removes people from who they really are.
What people have to realize is that their minds haven't been exercised enough. They haven't expanded their own mental "powers" to the point where they can experience a fuller spectrum of life. I'm not talking about something "induced," I'm talking about the here and now...the ability that our brains afford us that we've, all too often, become too lazy to use.
Spend some time working on building up your thought processes, and energy recognition. Play "games" that will help you realize that your mind hasn't been used nearly enough. Start to recognize things around you that you normally don't. Be aware, alert, and able. Enhance your mind by thinking about your abilities to use your energy to affect those around you, as well as yourself, in positive ways that you've never done before.
In about four or five months my new book will be out. It addresses a number of these subjects in more depth, along with exercises to help you achieve some of the things I've mentioned. In the mean time...don't think someone else has greater powers than you. It's just that you haven't uncovered them yet. Believe me - it's worth the exploration!
