If our thoughts create our reality then why are most people suffering? Why do not they get peaceful and richer and successful and lean and toned up by thinking their way?
Because our dominant thoughts create our reality. If you thought for a moment to be able to do a handstand before your beach vacation this year and the next ten thoughts were about how incompetent you were, guess which thought wins?
The goal is not to think one positive thought and do whatever negative you want to do; the goal is to think every moment in the manner you do not have to worry about trying to drink water. You know you will be able to do it.
That knowing and thinking and knowing and virtuous cycle creates all miracles.
