When these great cosmic bodies pass near the Earth, they also pass near us. When the Earth is shaken, it is not possible that the trees growing on it are not shaken. It is not possible that the human being living and walking on it is not shaken. No, everything is shaken, but the shaking is very minute, and man had no instruments to measure it with. Now however, we have such sensitive electronic instruments, that a vibration of a thousandth of a second’s duration can also be measured. But the vibration of the human being still cannot be measured. We have so far not made any instruments to measure this with.
Man is a very subtle creature and it is necessary for him to be that way; otherwise it would be difficult for him to live on the Earth. If he was able to experience and be aware of the influence of all the surrounding forces that act upon him twenty-four hours a day, he would not be able to live. We are only able to live because we are not aware of everything that is happening around us.
There is another law also. This law is that we cannot be aware of influences either above or below a certain limit. The range of our experience is limited. For example, suppose we measure the body’s temperature as being between ninety-eight degrees at the lowest point and one hundred and ten degrees at the highest point, that shows that we are living within these twelve degrees.
If the temperature drops much below ninety-eight degrees we will die, and if it shoots up above one hundred and ten degrees we will also die. But do you think that the temperature range of the universe is limited to just twelve degrees? Man lives within the limited range of twelve degrees – outside of this range he will die. Man lives in a sort of balance. He has to fluctuate between ninety-eight and one hundred and ten degrees. Similarly, there are balances for everything.
I am speaking to you and you can hear me. If I speak in a very low tone, a point will come where you will not be able to hear me. This you can understand, but you will not be able to imagine that there is a higher point of audibility beyond which you cannot hear. It will be difficult to imagine that a louder noise can also be inaudible.
Scientists say that we have a certain range of hearing, and that we cannot hear anything below or above it. All around us great thundering noises are occurring, but we cannot hear them. If a star disintegrates or a new planet is born, tremendous, thundering noises are created around the Earth. If we were to hear them, then at that very moment we would become deaf. But we are protected because our ears cannot hear them. We cannot hear below certain decibels and we cannot hear above certain decibels; we can only hear within a certain range.
There are even limits to smelling. The senses of all human beings operate within a particular range. For example, a dog is able to smell much more than you can. Its range of smell is wider; a dog can smell what we are not able to smell. What we are not able to hear, a horse can. A horse’s sense of hearing and smell is much sharper. A horse can smell the approach of a lion from a distance of one and a half miles. It will suddenly stop, and we will not understand why. Its sense of smell is very powerful. But if you had such a strong sense of smell that you could experience all the smells pervading your surroundings, you would go mad. A human being is closed within a sort of capsule – he has boundaries.
