How many people who openly talk about or write about awakening shakti have the real ability ?
ZERO
It is a forbidden subject. A disciple can know if the guru is spiritually perfected by hearing things that is not written in any books or Shastra this way
Even Vishnutirthji wrote in his prologue “i am a novice in this matter” and then wrote a detailed book devatma shakti.
One can.only speculate how much more information there is out there which we don’t know. And will never know
The science is a matter of experience not discussion. It is like building a rocket / space ship. You can read all you like about building one And think you can go out of space imagine it but your still on earth ! You need a guru who has built one !
