I thought I would add that a friend who had the same Guru...saw the Dalai Lama
and said she had an overwhelmingly high experience.
And come to think of it...Listening in the audience to Dr. Wayne Dyer,
bless his little soul,
I walked out as I would having listened to the Guru's devotees giving sat sang...certainly
the wonderful Alpha state...my brain waves were there!
Truth for just a few minutes can do that I find.
Is there an effect in large numbers...maybe, yes.
Can you get swept up in a crowd of spiritually minded people
with one focus?
