Baba always took two rupees as dakshina from purandhare. Curious about this he asked Baba why the denomination." I do not care for the monetary value of the money" , replied Baba ." But I want to stress Shraddha and saburi, So I asked of only of ten times Baba gave purandhare money that he carefully preserved in his place of worship and so did his son.
But what about the future generation? They may or may not know its value, So his grandson took all the coins to a goldsmith and got a silver statue of Baba made. He figured that the idol would be taken care off. The silver idol is worshipped daily.
