I think its interesting that he lifts up that when we say we try to go out of the body with different techniques we are actually focused on that the consciousness is only in our body/brain and as a consequence our beliefs create what we experienced as well.
One thing that was advised to me from the inner realms was to project myself everywhere and look back at myself when doing natural things. So if I am walking down the street I imagine myself up above on a roof looking down at myself, but i make it fun,so I may lay stretched out striking a pose on the edge of it, or on top of a pole, or walking down the street coming towards me.......whatever, but it's fun and quite surprising to see my body from different angles as usually it is a flat one dimension in a reflective surface. It's fun being on a moving train and seeing myself outside the window as we pass each other. I realized I was given this as a practice to get out of my body. It's fun for anyone to try, and it sure breaks up our day, and keeps our vibes up.
With time and practice we lose the 'split' consciousness and go fully as 'one', and then we can move higher up the more refined dimensions as we are more energized. When we move higher we can actually change things in our 3D level i.e. health, finance, etc. as we are more flexible with time lines.
