I suggest it is our attitude. I believe the mental creates the physical, never the other way around. I do not believe it is necessarily positive thinking because that is still trying to force change. I suggest it is simple acceptance of “what is”, gentle tolerance of others and trusting that which is beyond to evolve the better.
Actually, I do not believe there to be any separation between the mental and the physical. I believe the physical to be the manifestation in form of the mental activity underlying it. Collectively it determines the activity of the planet and individually that which each experiences. (or something along that line) 🙂
