radha baba and black money

i remember my old days when i was in my teen age. We used to sit with Radha baba and listen his speaches . Radha baba was supporting lot of families , their livelihood, their education and marriage of their children . We were also one of them . Therefore several times Radha baba was requesting for money to his disciples.The resources with Shri Bhaiji Shri Hanuman Prasadji poddar was not enough to meet all. He used to ask his followers to contribute some money . Mostly the people alongwith radha baba was salaried class and in seventy the salary of the persons were not enough even to meet their own experiences as each were having big families .
Radha baba was several time surrounded by businessman like singhanias , dalamias , agrawals etc which were crore pati at that time . But they were not of much help because Radhababa always insisted on white money, tax paid money.
It was his firm conviction that if the money given is not pious,earned from genuine means in lawful manner, it will have a adverse effect upon the person to whom the help is given . Therefore he said black money is harmful and should not be used.
such an high ideal was of that saint . very rare.
