Who can say? As yet, no-one has reliably documented the effect on individuals from group meditation practice of any kind.
The simple research proposal I made to John Hagelin a few months ago hasn't been done yet, at elast partly because research on microstates during TM hasn't been published yet. IF the research on microstates shows that there's some microstate pattern associated with TM, and more importantly, with pure consciousness, it may be possible to do "interpersonal" microstate studies. IF such interpersonal studies found something interesting, then they could be replicated by other researchers. IF such replications actually found something, then obviously researchers into other traditions would want to see if there was some kind of measurable "field effect" for other meditation practices as well. That's a lot of "IF"s... But wouldn't it be fun if...?

They are doing these large silent group meditations of three hours at a stretch each day with 5,000 meditators in attendance. A question is if they, the Yogananda meditators, are not showing the EEG Alpha coherence like the TM meditation does, are they kidding themselves and wasting their time sitting there? The Ontological Experiential Report coming directly from out there at the convocation is that the experience is very powerful as a field effect spiritually. -Buck
