There are several stories in which I heard people experiencing their subtle body leaving physical body for sometime and coming back into it.
One of them is HH Sri Siddheswarananda Bharati. He experienced his jiva leaving his body temporarily while chanting hanuman mantra with devotion for long time.
I heard this phenomenon in Yogis also.
But I never heard about such phenomenon in the persons opted for vichara/gnana marga.
Is there any person either in scriptures or contemporary days experienced the phenomenon by mere and intense vichara?
