Jain Acharyas had proven even more advanced facts. They have described a yogic method of super natural powers.
It is called Sambhinnasrotolabdhi. It is an excellent power by means of which the whole body becomes a sensory organ, an instrument. Then all this talk of the eyes seeing and the ears hearing becomes meaningless. With the manifestation of this power, every limb of the body works as the five sensory organs. The whole body can see, the whole body can hear. Some people read with their fingers... they perform the work of the eyes with their fingers. This phenomenon has bewildered many scientists. They cannot deny the obvious. They cannot say that one cannot read with the fingers. And yet they are not able to explain how and why it is being done so. This topic is still beyond science and scientists are still trying to understand it. But this concept has been accepted many centuries ago that the whole body performs the activity of the sense organs. One sensory organ can perform the job of another or we can say that the whole body may be used as a sensory organ.
