What is the root of that Primordial Vibration?
NO ONE KNOWS.
You can reach upto that throbbing Vibration in the process of Samadhi when you crossover the barrier of Time & Space.
But when you return, you can never express that state in elaborated words.
What most is stated by All those Visitors is ‘ Light & Bliss “.
