All the religions interpret the concept of hell or heaven as per depicted in the holy books of their own religions.If we go little bit above these descriptions.i feel, it is simply a notion that those who accepts life as it comes and do not interfere the natural flow of gods orders and they have been chanting the name of god every moment in their hearts,they are just in heaven and vice versa in hell.There is no specific place where the god sits in the court and evaluate the sins and good doings of the masses.
