Chi - Qui/Ki/Qi-Gong - PraNa -

Yoga Sutraas by Patanjali and Yoga Pradaapika talk about it.

This is very scientific and Western Science still has ways to go but thanks to work done by Harvard in last decade, on some monks, and soon followed by some other Universities of the West, this is getting accepted in the West.

Einstein said Mass Modifies 4D Space-Time, and the Space-Time Warping is the cause of Gravity. He did not get everything right, and Energy causes the warping of the Space-Time, and Gravity is not the caused by the Warping of the Space-Time, but by the Energy, which is fundamentally not as many as the Western Science says it is and still spending Billions to confirm some. But that is a separate topic, and I have a small experiment on self to demonstrate that the Energy modifies the Space-Time.

This knowledge has been maintained in the mountains of Tibet, China and India but lost in the valleys because it was banned by the Britishers as they could not comprehend it and thought this was a Black Magic.

There is no magic to it, and only a sincere seeker, with ego burnt, to mind to set the the Ultimate Reality, can realize this. There are no powers, but the surrender and tuning to that Reality like a "cleansed and fine-tune tuner"

I know many of you would be in disbelief, and that is your ego and a closed mind thinking. Seeing and experiencing is only the real believing.
