I think the videos are wonderful and Robert is to be wholeheartedly congratulated for having the courage to put his face to his message and posting them.
I particularly like how he underlines how BapDada has created bad karma for himself by giving false advice. That is an area we have not covered.
I guess the questions that arise to your concerns, Gupta, is
a) does mental or emotional energy have any effect at a distance, and
b) by what medium or mechanism?
I would tend to say "yes" to the first but have no idea how or to what extent in the second case.
But how much of what we think might be happening in the first case, is real and genuine and how much is fear, suggestion and internal projection?
I am still here. You've survived Gupta. I have not listen to all of Robert's videos but I am suspecting he fells absolutely protected by a "greater light" or other spiritual influences.
He outlines BK practises for outsiders in another video. These are all good introductions for people, eg far easier to gain an overview than from this site. I hope he does some in Chinese, if he can speak it.
