Throw Lane overboard. See if Harold Klemp's accounts tally with Twitchell's or even Gross'. Present your findings. We can then debate. All i care about is whether your findings on Sudar Singh and the like can be replicated by outsiders.
Replication is really helpful to secure a finding.
You don't think Sudar Singh is instrumental. Yet, if Twitchell is to be believed, then Sudar Singh was the link between him and the Vairagi Masters. If Twitchell is lying, then it speaks volumes about the integrity of his movement. Keep up the work. I want to go back to the home base now.
