You project your reality
The world is continuously created by your beliefs, like a projector’s image. You yourself are the creator of everything around you — problems, situations, and events. They are reproduced from within you.
It’s like a movie you’re so immersed in that you forget about the reality around you. Similarly, absorbed in your own thoughts and perception, you forget that another reality exists.
Meditation helps you see not only the results of thought processes, but their flow.
