Neem karoli baba

[Goldenwings]

Ram dass said that the moment that changed his life is when neem karoli baba told him what he did by the lake

This same story is repezted through history related to many Saints, that can tell you some things you did in the past

Some claim that they do that with the use of a Demon that tells them what did this person do

Im really curious, how do they do that ?

Thanks in advance
