Hmm... I do not see anywhere "do not understand it in a better way and jus like how your father thought"

Or does Preserve mean do not take it to next level....
Actually weather you accept or not.. changes happen

See the religion is still the same..
Number of people following it the true way changed (reduced if I could say so)
Number of people breaking the rules increased... and came up with "this is acceptable" attitude...

Hard Work Doesn't Kill Anyone... But Why take Chances.
