Yes...but it is not what i was asking....
I know that there are these brainwaves etc....
BUT you wrote about this convinced Indian guru....
HOW HE KNOW HOW TO MEDITATE ??????
WHO TOLD HIM WHAT HE HAVE TO CREATE IN HIS MIND TO GET INTO STATE ?
is this spiritually genesis of this ?
HOW HE KNEW HOW TO get into state? I KNOW THAT THIS IS POSSIBLE... but someone had to dicover how to get into it....how it was discovered....is this knowledge from occult side ?
