Hare Krishna ! Dandavat ! PAMHO !
As Srila Prabhupada in his books have recommended that grihasthas should spend minimum 50% of their income in preaching KC Movement. When I told my parents about this, they said that 50% is not possible in this age, how will u discharge your family duties and liabilities etc etc. As i learned from many sources on internet that 10% is the the most accepted term in various religion like in Christianity they call it "TITHING" and in sikkhism it is 'DASVAND". Though I don't know if any vedic text too recommend such specifc % number to keep aside for Krishna.
Now I want to know whether Srila Prabhupada's recommendation over this was for all future devotees irrespective of time/place/circumstance or it was only for his disciples at that time when he was physically present.
