Have you seen the movie Guide of the Great Indian film Actor Devanand ,wherein he has been forced by the people to become a saint and really he became a saint,though he was cheating the people earlier.The Case of Nirmal Baba may be the same.Probably ,we would have forced Nirmal Baba to become a saint,and the rest would have been his fate.However,We should not pass comments on him as we do not know the will and wish of the God as the God is the supreme Power,the one and only one dictator,who allowed numerous of fools to win in elections ,granted them more than enough facilities and Powers to rule over India/states and allowed them to be corrupt.This is why the great saint Meera Bai told"
"सन्तों करमन की गति न्यारी,
मूरख को तुम राज दियत हो,
पन्डित फिरत भिखारी"
Meaning-"O saints/followers of the God please listen-The good works we do on this earth is always fruitful.As you(i.e. the god) grant Kingdom to fools and scholars to roam around like beggars"..
