An interesting trivia…
Kaleidoscopes may be beneficial to your emotional comfort. Do you remember how pleasurable looking through a kaleidoscope was as a child?  Have you looked into one lately?  A well designed kaleidoscope can give health and you those same feelings. But is there more?

A two mirrored kaleidoscope creates what is called a mandala. Mandalas are considered to be beneficial to healing and are often used in meditation. In addition, kaleidoscopes use colored objects. Color affects us although we may not be aware of it. Color therapy (refer below for information on colour therapy) was developed long ago and is being used in alternative medicine. By choosing the colors used in a kaleidoscope and the correct mirror pattern, the kaleidoscope could be considered an instrument of healing.

Skeptical?  Think how you felt when you last looked through a kaleidoscope. If you are like most people, you spent some time looking through it, thinking about the pretty shapes and colors. You may have noticed how "addictive" watching the images could be.

While there are no scientific studies to about the beneficial aspects of kaleidoscope viewing, if nothing else, it is a relaxing and enjoyable way to spend a little time. It is well known that relaxation techniques are good for us. Think about keeping a small kaleidoscope on your desk at work and using it for mini-breaks to relax mind, soul and body.

The soul always lives in color. Color is as necessary to the soul as air is to the body. When we take away the motion of light or color, we have no awareness of the appearance of matter. We receive all knowledge of the Universe through this electromagnetic radiation. White light contains the energies of all elements and chemicals found in the sun. This white light of the sun is absorbed from the atmosphere by the physical body and is split into component color energies, which in turn flow to different parts of the body to vitalize them. Light is a force stimulating growth; every living thing depends upon it to build and maintain its form. Light brings about chemical changes in the body. Therefore, light, whose source is solar energy, is one of Nature's greatest healing forces.

Color can help to restore balance when a blockage of imbalance of this energy has resulted in disease. The use of color can help to restore vitality to the etheric body through the projection of specific color rays, which are then absorbed by the chakra centers. The pituitary gland transforms these colors into revitalizing energies to rebuild the centers that are lacking in energy. Color healing shows us how to make light work for us. The use of color is one of the many natural tools available to help us walk in balance with Nature.
