A guru’s work in the world is to alleviate the sorrows of mankind, whether through spiritual means or intellectual counsel or will power or physical transfer of disease. Escaping to the superconsciousness whenever he so desires, a master can become oblivious of physical illness; sometimes, to set an example for disciples, he chooses to bear bodily pain stoically. By putting on the ailments of others, a yogi can satisfy, for them, the karmic law of cause and effect. This law is mechanically or mathematically operative; its workings may be scientifically manipulated by men of divine wisdom.
