I have been listening to Jose's primal beta beat for a number of years and like the way he keeps things simple. It really is just me, myself and I alone in this world first. Once we accomplish our own connection to what matters then we are ready better able to include others in our world.
Personally I 'go to level' to level myself - not for any other purpose. Once I'm done, usually 20 minutes, I just feel balanced and more alive. Like anything, I take this process in moderation and don't expect too much. Then I'm satisfied with the results.
It would be fascinating to fast forward another century to see how far along we - as a species - will have evolved in mind control - or as I call it - mind connection. To me it's really all about making that clear connection between myself mentally and physically. We have so many outside forces pulling us in all directions that it's far too easy to follow misdirected paths.
As we age the more opinionated and rutted we get. By going to level and focusing on relaxation, I find the peace and tranquility missing from most of life. Opening up inside allows me to open up better to my world.
