We are not able to discover anything new, completely different, that is not in the realm of our perceptions. All knowledge that is attained by way of scientific instruments and our senses is processed in the brain and forms within us, apparently, a picture of the world around us. If we were to increase the frequency of one of our senses, for example, if we were able to see by x-ray vision, or we were able to hear sounds that exceed the normal sound frequency, the world around us would appear completely different.
All sciences work with the research information that is obtained by means of our five senses.
However, the Kabbalah, in contrast to other sciences, works with obtaining information that is beyond the limitation of our senses and with that we research the world around us. Only a portion of the waves that exist all around us makes an impression on our ear drum. It becomes elastic and our inner mechanism returns it to a state of equilibrium by an opposing resistance. The brains measures the strength and frequency of the membrane's movement and translates this influence into 'hearing' information, and it is relative to us. This implies that our response is secondary to the original environmental influence.
