Lord Krishna is perfect

Om purnamadah purnamidam Purnatpurnamudacyate |

Purnasyapurnamadaya Purnam evavasisyate ||

“The meaning of this verse is that although everything emanates from the personality of Godhead, He never diminishes. Here on earth petrol is running out, and this is becoming a terrible problem, but the Sun is still shining and will continue to shine for an untold number of years. And Krsna can create millions of Suns; He has already done so.” Krsna is so perfect that if you take from Krsna all of Krsna’s energy, all the energy is still with Him. That is perfect conservation of energy.”

It should be noted that being the devotee of 'Krsna', he regards god 'Krsna' as similar to "Brahma"-the 'ultimate reality, the Omnipotent, Omnipresent and Omniscient, the ultimate source of everything. The literal meaning of the mantra is that "if you take whole ( purna or Sunya = 0) out of the whole, it remains whole." The universe being a system of perpetual motion behaves like a "whole", inexhaustible and is self-sufficient in matters of matter, motion, and energy. The bugaboo of energy crisis arises due to ignorance of man of the true nature of energy, and of Nature's Majestic arts like perpetual motion that can create matter and energy out of 'nothing'.

In this world, we are limited by our thoughts. It is natural for anyone to be partial to one's own ideas. But because of this partiality, we often fail to recognize that the idea of others may be bigger and better ones. When we learn to be open-minded and not opinionated about anything, we grow in understanding and wisdom. A person is mentally free when his judgment is no longer influenced by the prejudice, custom, conventions that are imposed on him by the environment, his natural and rational background.Alas! open-mindedness and impartial inquiry will remain the myth of science as long as false theories like relativity and thermodynamics continue to rein science, and on the other hand, perpetual motion and free energy concepts continue to be suppressed by science and vested interests.
