Then let me tell you a story , usually several big temples have some fixed men in the pujari attire who try to take money from you by various means , so when I was a kid my mom visited one such temple , a pujari literally blackmailed her into giving him money , saying that bad things will happen to me if she didn't give him money , so yeah . Very many places have these crap while others focus on charity for example the Ram Krishna Mission , or like the Dakshineswar temple is such a nice peaceful place which exists for worshipping without any sort of con artists in its vicinity .

Also you should watch PK . It really does question several things about the gurus and stuff while . The movie is kinda an attempt to distinguish between religion itself and the con artists of religion all under a comedic film
