Everything in the Universe is vibrating. Even light is vibrating (different frequencies of vibration give us the different colors, just like different frequencies of vibration give us the different notes in an octave of sound).
The so-called 5 physical senses, touch, smell, hearing, taste, and sight, are all biological “sensors” that, for the most part, detect vibration in different ways. While smell doesn’t directly sense a vibration, it is directly sensing physical objects in the air, that have different vibrational parameters. Each sense perceives vibrations within specific, limited frequency bands. For example, through the sense of hearing, most people perceive vibrational frequencies in the 20 to 20,000 cycle per second range – we call that “sound”. The eyes pick up much faster vibrations that we call light.
But these 5 biological sensors we use, only pick up a very, very small part of the infinite vibrational frequency spectrum. There are other frequency bands that the 5 senses cannot perceive, which puts a BIG hole in our information about what is REALLY there. And for most people, this very limited data from the 5 sensors is the only thing that allows them to be in touch with the world around them. We are, for the most part, virtually blind in this Universe.
Humans have built machines that pick up some of the vibrations we can’t get with our 5 senses. These machines translate what they pick up into the range that we can get with one of our senses. For instance, our eyes don’t pick up on x-rays – they only see the slower vibrating visible light range. So we made x-ray machines that take pictures to show us the result of using the x-rays, on a film that we can see with visible light.
Can you imagine being able to see such things as x-rays and gamma rays all the time? Radio waves are also in a vibrational frequency band that is not within the range of any of our senses. The circuitry in a radio or TV changes these vibrations to frequencies of vibration our senses of sight and hearing can perceive. There are many other things that we do not normally perceive. But all of these things, and much, much more, are available for us to perceive when we transcend the limits of our separate self.
