Potential energy and Kinetic energy

Dear Readers,

Radhekrishna!!

We have already discussed two out of three stages with respect to the proportions of potential and kinetic energy and the following were the conclusions:

In the first stage (Vaikuntham), the proportion of potential energy is 100% whereas that of kinetic energy is nil.

In the second stage (Devalokam), there is a continuous transformation from potential energy to kinetic energy and vice versa.

Now let us see what is exactly the case in the third and the last stage i.e. Bhoolokam (the world of human beings).

The Bhoolokam (earth),

On the earth, the value of the variable, ‘height’ (h) in the formula

P.E. = mgh is ‘0’

Hence, PE = mg x 0 = 0

Now if the total of P.E. + K.E. has to be 100% always, then it means that at this stage, the proportion of kinetic energy has to be 100%. This in turn means that all the energy that human beings (who inhibit this world) have, is in the kinetic form i.e. owing to their motion.

Thus, on earth we human beings have zero potential energy. We do not possess the powers to lift our bodies by ourselves and fly above the ground in the sky i.e. we don’t have powers to defy the gravitational force (g) exerted by the earth on us. The influence of this force on us constantly keeps us on the ground. But in the ancient times, the rishis, with the power of meditation and yoga, attained powers that could make them fly in the sky thereby defying the gravitational force.

In the seventh incarnation of Lord Vishnu, in which he was born as the son of King Dashratha as Lord Rama, there is an incident when the brother of Lord Rama (Lakshmana) gets severely injured in the battle with the army of Ravana and the vaidya (known as a ‘doctor’ in today’s world) advises that a particular herb called as ‘Sanjeevani’ which was found only on the mountain named ‘Nilgiri’ in the Himalayas be brought. Now this herb had to be made available overnight! So at that time the devotee of Lord Rama, Hanuman, (who is the eleventh incarnation of Lord Shiva) rises to the occasion and flies all the way from Sri Lanka to the Himalayas and back in one night’s time to get that herb. Now several people, especially Indians, know all this as they would have heard this as a bedtime story from their grandparents.

But the mentioning of all this, in this article of ours, has a different purpose altogether. The point to be noted from the above incident is that how was it possible to get that herb in such a short time? The answer, if put ‘scientifically’, is that Lord Hanuman converted his body mass into energy, which helped him move at the speed of light thereby facilitating the successful accomplishment of the task, overnight. When a body (mass) is converted into energy, it can travel with a very high velocity. The above incident was ‘just’ another example of conversion of potential energy into kinetic energy.

In our next article, let us see that what is the interpretation of zero potential energy and 100% kinetic energy at this third stage (ground level) or (earth), in hinduism.

Till then do Guru Dhyanam (reflecting on one’s Guru, continuously thinking about one's Guru; and enjoy the real bliss). Radhekrishna!

Sarvam Guruvarpanam
