Just like Ratnakar he was chanting murder! Murder! Murder! Kill kill kill in Sanskrit which was Mara! Mara! Mara! Chanting a word which, he was a murderer, he was a robber. When you chant it in sequence mara mara mara it becomes Rama Rama Rama. Chanting Rama even when he was thinking something else it still worked. It is like fire. when you put your hand in the fire whether you believe it or not  you get affected,  somebody does chant somehow with an open mind if they just chant they will feel some diference from it,

You believe it or not you get affected!
