i are basing your knowledge on here say and movie;s
yes maybe the movie is based on a true story but thats all jus based it may not be 100% accurate.
its jus like 10 men see;s a car crush the story will be the same a car crashes but how it crashed each one will tell you a different story.

swapneshwari is very powerfull and will protect her.
as for the aghories it is a part to worship lord shiva but very very few are real aghories, aghory masters for there last test to show there faith cuts there own neck and because of there belief in shiva and there worship they would come back alive.
thats why there are very few aghories because few ppl would do that and even fewer ppl would be successfull ok.
but after doing that and aghory becomes one with his master lord shiva so just hurting someone is not there way.


right next part there is a sadhana to bring back a dead corpse but and i say but the corpse has to be at least ten days old.
besides that there is plenty rituals to go with it and selection of a corpse has to be good and the corpse had to die by sucide which means his time to die had not reach yet so yamaraj could not come for the soul.
a second thing is dat you wouldnt rise a corpse to b a snake chramer thats wat u do all dat ritual for jus so he can worship naag baba.
but it have ppl who is living who does worship him it doesnt make sense.
