The same holds true for other sense-organs too, each having its inherent limitation of sensitivity. The eye too, like the ear, can grasp the image within its perceptive range (from .00007 to .00004 cm. wavelength). Thus, we cannot deny the existence of images or forms in our surroundings just because we fail to perceive them on account of our limited visual range. The images on TV screen are its example. The TV has an arrangement within itself to catch the high-frequency waves that are invisible to us directly and to convert them by rediffusion into an image on the screen that is visible to our eyes.
Now, if it were possible to so alter the sensitivity of our eyes and ears that they begin to perceive those impulses which normally remain beyond our range of perception, there will be complete change in the scenario of the world around us from what we have been conditioned to see and hear so far. The yogis state that after certain breath-control exercises, one ceases to feel the ground on which one walks, because the range of sensitivity of our skin to grasp the electro-magnetic waves that generate the sensation of touch gets altered. Referring to the dangers involved in the practice of yoga without proper guidance or expert supervision especially for the newly initiated who in their enthusiasm are likely to overstep the limit, a yogic teacher, (most probably Mr. Selvraj Yesudi, whose book ‘Yoga and Health' has been very popular in Europe) has mentioned an anecdote of his personal misadventure at an immature stage. Instead of a gradual increase in the duration of breath control exercises, he once undertook a rather strenuous stint of yoga lasting over forty-five minutes at a stretch at the end of which, when he tried to get up from the sitting posture, he suddenly noticed to have lost the sensation of touch in his feet. This alarmed him considerably and it was not until the normal sensations returned after fifteen minutes that he could breathe a sigh of relief.
