Ah. In that case, mostly no. I've seen no evidence to support any magical beliefs.
Oriental philosophies have nothing to do with magic. They teach us how our thoughts and actions, their causes and the consequences should be in harmony with nature and universe.
the related thing I have seen, is that it is very common for people's assumptions, prejudices, and mistaken impressions of the world, to cause them to blind themselves to what is actually real. Thus, depressed people tend to fail to notice the positive things in their lives, and overly happy people often fail to notice when sadness is troubling some who are near them.
It has nothing to do with beliefs or religion, but personal characteristics. We become blinded not by religion, but by our own egos.
I find that it is true that small steps such as training your "resting face" to reflect a positive or at least calm demeanor, will decrease the number of people who react negatively to you at first sight.
But no matter how much someone meditates, or "focuses energy" on something, that something wont be affected.
None of those philosophies claim that you can change or affect "something" by meditation. You can change only YOURSELF, the way how you think and perceive surrounding. I meditate with purpose to focus my own thoughts, to clear my mind. It helps me to see things more objectively, not blinded by current emotions, biases and my ego.
But people who do believe in such things WILL tend to think it has been proven true, because since they will WATCH for positive things to happen, and attribute them to their focusing work or prayers, since there are always positive and negative things happening, they will find their reinforcement.
Smile to people and they tend to smile you back. Be angry at everybody and everything and you'll see how people become angry at you, simple as that. The energy you create will be projected back to yourself.
