Some claim their is a hell some claim they isnt .... by rama singh had darshan of hell and other gursikhs have claimed to have aswell.
From my knoweldge hell is considered as like a plain for punishment depending on the evil actions commited by one on earth. Apprently Jamdhoots also do exist, once your avastha is high enuf u can actually see the jamdhoots or other people who are near to time of death can also see them.
Find some Jeevenwale Gursikhs who have created a jeeven and have actually expereinced other worlds and have darshan of shaheed singhs and guru ji on a regular basis.
I am not saying their is a hell or their is not as one has limited knowledge
but their has been paranormal experiences in all countries, from ancient history to present. which have still not been able to find the bottom of.
