He would lie down on the floor and pretend he was asleep. Then he would explain that if an enemy approached him in his sleep, and attempted to strike him, his sixth sense would instantly respond to the danger. He would awaken and his whole body would automatically respond to the attack. He demonstrated this by tensing up and curling his whole body while preparing his arms and legs to deflect or block any oncoming blow. Concentration is of foremost importance when learning Silat.
Concentration is viewed as a way of becoming in tune with the sixth sense.
The other way is from receiving it from ones guru. It is possible for a guru to pass on his power to his students. This is sometimes enacted secretly by the simple and subtle act of exerting pressure with the fingers when a guru shakes the hands of his students. There are therefore two ways of procuring inner mystical power. One is through the process of the student practicing the movements of Silat and learning concentration through meditation.
