Human mind has some limits. It is our biggest mistake to believe that our mind is the center of our intelligence, but in reality, the mind is just the topmost layer covering our potential and intelligence. We have with us many centers, which are of much more power and intensity of intelligence.

Whether we call them our inner minds or hidden centers of various powers, it does not make any difference. But the mind in which we live has its own limitations and due to its limitations, man is so unsuccessful.

A human being is a creature bound within certain limits. We can hear loud sounds, but if the sound gets louder, then after a certain limit we are unable to hear the sound. At this moment, there are so many vibrations going on in the Universe, producing so loud a sound that even if we hear those sounds for a single moment, we would die. But we cannot hear these noises, as they are not within our hearing range.

In the same way, if someone starts talking in a very low voice, then after sometime, he might speak in such a low voice that we might not be able to hear his voice. This is because we can't hear sounds that are below a certain limit. Millions of vibrations are constantly occurring in the world, but our ears can hear only 32,409 types of vibrations (tremors).

Even our eyes have certain limitations. An aircraft flying in the sky slowly moves away from us. As it moves away from us, after some time we are unable to see the aircraft. The aircraft has not vanished, it is still flying, but it has gone beyond the limit of the vision of our eyes. In the same way, if some object comes very near our eyes, then also we are unable to see the object.

Same is the case with temperature. What is the temperature of the sun? If we ask this question to a scientist, he would say that they cannot measure the temperature of the Sun. On the snow covered slopes of the Himalayas, what would be the temperature of the deepest layer of ice? How many degrees below Zero? No scientist would be able to answer this question as well.

Our body can endure a temperature within the limit of 92° F to 108° F. A human being is thus bound within limits even in the case of temperature. In the vast rage of temperatures of this world, we exist only between temperatures within the range of 15-16 degree centigrade. If the temperature varies above or below these degrees, we are declared dead.

Where there is no mind, there cannot be any agony, worry, grudge, enmity, or any kind of rupture. Where there is mind, we have tyranny, turbulence, disturbance or persecution. There is a disturbance in life. If we try to focus on the knowledge that we possess, we just have some good and bad incidents in memory and worries of future. This is what we call as knowledge. Only this is the asset of our life, and in reality it is responsible for the destruction of our own selves at the end.
