Swamiji, how should a student prepare for exams to get good marks?

[A question by Shri Sathi Reddy]

Swami replied:- Q=E+W is a law of thermodynamics. Q is the heat supplied to the body through food. E is the rise in the internal energy that consumes a part of heat. The rest heat is consumed by the work (W) done by the system. If E consumes all heat (Q=E), W becomes 0. It means that if the tension raises the E so that all the Q is consumed, the brain will not work and the student fails in the examinations. The answer is printed in the brain like the information stored in the disc of the computer, but it is not displayed on the screen since there is no current.

Similarly, the answer is printed in the brain as soon as you hear the teaching in the class and the answer will be displayed on the mind-screen if Q is not wasted in raising E and is stored well. This means that if you don’t have even a trace of tension in life, the answer heard in the class will be displayed on your mind and there is no need of reading any book after hearing the teaching in the class just once. Krishna told the Bhagavat Gita even though the war-atmosphere was causing a lot of tension in every body. But, in the case of Krishna, the external tension did not raise at all even a little of His E. His Q was also very high due to the eaten butter in His childhood, which is a precious energetic food. In such condition, His W was always at the climax and hence, the excellent Gita came out even in the atmosphere of high tension.
