Human life in society is based on morality(consistency against adverse questions). M k Gandhi saw world human history as full of immorality,imperialism,reactionary and anarchist. So he complexed all above four to usher social(knowledge) in self for heaven on earth. There may or may not be heaven after death. But there should be heaven on earth. And m k Gandhi ushered it.

When people are having CONSISTENCY AGAINST ADVERSE QUESTIONS,then those people enjoy heaven.
Otherwise it is hell.
