Out of many types of mystic performances for self-realization, the process of jada-yoga is also one accepted by authorities. This jada-yoga involves practicing becoming like a dumb stone and not being affected by material reactions. Just as a stone is indifferent to all kinds of attacks and reattacks of external situations, similarly one practices jada-yoga by tolerating voluntary infliction of pain upon the material body. Such yogis, out of many self-infliction methods, practice plucking out the hairs on their heads, without shaving and without any instrumental help. But the real purpose of such jada-yoga practice is to get free from all material affection and to be completely situated in the self. At the last stage of his life, Emperor Rsabhadeva wandered like a dumb madman, unaffected by all kinds of bodily mistreatment. Seeing him like a madman, wandering naked with long hair and a long beard, less intelligent children and men in the street used to spit on him and urinate on his body. He used to lie in his own stool and never move. But the stool of his body was fragrant like the smell of fragrant flowers, and a saintly person would recognize him as a paramahamsa, one in the highest state of human perfection. One who is not able to make his stool fragrant should not, however, imitate Emperor Rsabhadeva. The practice of jada-yoga was possible for Rsabhadeva and others on the same level of perfection, but such an uncommon practice is impossible for an ordinary man.
