The Source of Life

Q122: Swami!  in the big human body, where is the source of life located?

Bhagawan: You think it is the heart.  No.  Don't you know that today surgeons can do heart transplants also?  Even while it is done, the patient doesn't die.  Then where is the life principle that keeps you living?  In the spinal column between the 9th and 12th vertebrae, there is the life principle that acts as the main switch.

In the mantrapus pam, it is clearly indicated vidyullekheva bhasvara, a lightning or electric current acts as the life centre.
