Let start like this that we all have urges and thoughts that cause us to do terrible things but if we could help ourselves by not getting lost in the urge and thoughts not trying to push it away (that is the worst thing to do it only makes the thought stronger and stronger) but only realizing we have these thoughts and we cant help it that we have these thoughts, and to look at the thoughts and urges from a birds eye view then we wont feel a need to act upon those urges and the thoughts
The point of mindfulness is to be aware of the thoughts and the urges not to be judgmental about them not to say its bad to have it and try push it away just watch the thought as it crosses your mind realize the sensations in your body, where you feel it what is the intensity of it
that is the long and short of mindfulness
there is ways of practicing the technique to be good at it that when the issues arise it will be easy to put it into pratice
just a few examples
1 breathing meditation- go to a quiet corner everyday the same time same spot (start of simply 5 min a day and gradually build it up) and just breath in through your nose and let it out through your mouth and be aware whats happening think about the oxygen going in realize your stomach filling up and emptying out just be aware of whats happening
2 i felt it worked for me the best i went to the park and was just being more aware of the noises i hear the sights and colors i saw the feelings i felt from the bench i was sitting on just being more aware
its worth trying
it will help in many areas
