BTW, looking a your avatar, are you a karateka too?
No, I believe more in defending/protecting yourself by keeping the right mental attitude. Not even the best martial artists can beat you then. Mind over matter. But practising martial arts is probably good physical and spiritual exercise, much better than normal sports…
Quote: “...the right attitude not only has the power to turn every circumstance to advantage but can change the very circumstance itself.
For instance, when a man comes to kill you, if you remain in the ordinary consciousness and get frightened out of your wits, he will most probably succeed in doing what he came for; if you rise a little higher and though full of fear call for the divine help, he may just miss you, doing you a slight injury; if, however, you have the right attitude and the full consciousness of the divine presence everywhere around you, he will not be able to lift even a finger against you….
I have had innumerable examples of the power of right attitude. I have seen crowds saved from catastrophes by one single person keeping the right attitude. But it must be an attitude that does not remain somewhere very high and leaves the body to its usual reactions. If you remain high up like that, saying, “Let God’s will be done”, you may get killed all the same. For your body may be quite undivine, shivering with fear: the thing is to hold the true consciousness in the body itself and not have the least fear and be full of the divine peace. Then indeed there is no danger. Not only can attacks of men be warted off, but beasts also and even the elements can be affected.”
