What someone needs to do is a drishti experiment with non-BKs with no "spiritual" or spiritualist background ... have a load of non-BKs stare at each other between the eyes and see what happens.
Of course, *some* science has been done. Earlier I posted an article about scientist's studing "how to make someone fall in love (approx)" and their discovery that staring in the eyes helps. We cannot exclude that component. We cannot exclude the simple component most will have experienced of a mother or Father staring into the eyes of the baby, arguably part of the infantilization - pedomorphosis ... or whatever you might call it - of the BK experience where adults are encouraged to stay children to their leaders.
We cannot exclude there being hypnotic element and, I would argue, we cannot exclude that some other "psychic" or "yogic" effect on some psychic or "energetic" level ... all of which "science" would have a fit at the idea of.
One theme that is arising on this forum recently is that there are two things going on in Brahma Kumari-ism. One on a natural, personal level that produces spiritual experiences and highs ... and another behind that which is using or taking advantage of those natural highs.
Whether one looks at this in a metaphysical manner ... which the skeptics would instantly dismiss and use to discredit one ... or on a psychological manner ... for example, as sociological undercurrents within the movement ... it does not really matter to me.
Like "the language of dreams" ... which the very same skeptics would also dismiss ... the poetic, metaphorical language is, to my mind, really the best and only language we have to discuss these things.
Either way, they - and other critics within the religion such as the PBKs, both point to the same thing. There is more going on that meets the eyes ... and one should keep one's feet on the ground (... and wallet in one's pocket).
