Mind Body Aware Games provides you the best apps to travel up and down your inner realms, as well as forward, back, etc. Focus on your reality as well as the reality of what others experience. You are the captain of your inner travels. Feel Love and acceptance.
Do this sitting down, or with the gentle exercises provided. By thoughtfully exploring myself from within, I learn ways it works, and try to make personal changes. This is a common idea to all meditators, but these apps make it more explicit by leading you through some of the specific internal movements.
