We see with our eyes and hear with our ears, but how do sight and sound arise?

One life energy flows throughout the world, and there is nothing lifeless. Man has life. Even a grain of sand has life. A double movement towards and away, combining and separating, is called the life of things. Experiments prove that even dry wood has life. We may not believe it but scientists prove it. They have claimed that the life current is an ethereal vibration. They have felt that vibration with their own sense organs. They say that atoms were created from it, and molecules from atoms, and from molecules this world and universe.  The seen and the unseen derive from this ether, they say, and ether is everywhere.

The ether is endless, boundless, but its vibration has an origin. The vibration circles the earth seven times in a second. Another vibration arises and we experience both. The two vibrations give rise to a third, a fourth, and so on. When the number reaches 4000 million per second, a man’s brain becomes affected, and he sees red. As the intensity goes on increasing, he sees yellow, green, blue, etc. But when the 4000 million vibrations are doubled the optic nerve fails to react. Light moves 186,000 miles in a second. It is another wonder of sight. To a certain extent man can conceive these things, but he cannot see them with his own eyes.

Now let us speak of sound and the auditory nerve. We feel air pressure even 45 miles up in the atmosphere. Light is carried in an ethereal vibration, but sound in a vibration of air. There is a membrane in the ear called a tympanum. Where there are less than 30 vibrations in the air per second, this membrane cannot catch them. When the sound vibrations reach 30,000 per second, the sound is unbearable, and as they go higher, they cannot be heard at all.  So our auditory nerve is sensitive in the range from 30 to 30,000 vibrations. Otherwise it is inactive. There are supposed to be a few hundred thousand deaf people on the earth, but we are all deaf to a great extent. Our hearing range is small.

Men are never satisfied with little. They crave for bigger and better. With this urge they have made instruments of seeing and hearing that increase their range and enable them to see and hear what they otherwise would not.

Copernicus discovered that the earth went around the sun. Galileo supported this discovery with a telescope. Now we have telescopes by which we can see many marvels of the heavens. Mercury is closest to the sun, and she is 36 million miles away. Our earth is about 90 million miles distant. Pluto is the farthest at a distance of 3,700 million miles. These have been revealed only by telescope and spectroscope.

Scientists have been able to see things both big and small in their telescopes and microscopes. There is also a science of bacteriology. Through microscopes bacteriologists can see thousands of germs moving in a drop of blood. They have found that the red corpuscles of the blood are 1/3200″ in length; while white ones are 1/2500. There are five million germs in 1/625 of a square inch.

We have now a new instrument by which we can catch ethereal vibration from any point and manifest it. In 1925, one British scientist put this to practical use in the television set.

We receive sounds by telephone and telegraph and radio over long distances. Samuel Morse is the inventor of the telegraph. Alexander Graham Bell sent the first telephone message in 1875. German scientist Henry Hertz discovered how ether carried sound. Jagadish Chandra Bosu and Gulmiego Marconi made wireless. Their work has brought us the radio.

Light and sound are easy enough matters for us to understand now. But men often like to twist simple things and make them difficult.

Yaigisabya knew his past ten lives through meditation. Abadya asked him, “You have gone through so much evil and good in ten lives. In which life did you have the most pleasure?” Yaigisabya answered, “I didn’t have pleasure in any of them. Until we have salvation, we have no pleasure.” Men always look for emancipation and bear the highest aim in their minds, even if unconsciously.. That is why they often look at things distortedly and try to elaborate them into what they are not.

In the eye there is the transparent white eyeball which is covered by a fatty cornea coating, plus the dark centre, plus the retina in which there is distribution of visual nerves which are the main instrument for causing the visual sensation. The drum of the ear is connected with auditory nerves which are mainly responsible for auditory sensation. But the eye and ear are not self-acting instruments. Behind them there is the mind. When the mind is attached to eye or ear, then alone we see or hear. One Hindu philosophy says that what we see with our eyes and hear with our ears is all in the realm of ego.

We can understand men in two ways: by looking at their complexes and by making manifest the Supreme in them. Our ancient seers adopted generally the second path. Complex and Supreme, Matter and Existence, are one and the same, but we usually differentiate between them. The Hindu philosopher Kapil who realized the One, understood the foundation of seeing and hearing. Everything in the world is a manifestation of God. If we reach Him, we can realize the world. How to reach him? Wise men wrote ages ago, “To realize God we need daily spiritual practices and adherence to a living spiritual Guide or Guru,”
