There was a sermon by Oka Kyugaku. One of the things he said was that Sila, moral behaviour, to be reasonable about things, to be honest, to be self-restrained and so on, seems to be unnatural and forced. It seems to be unnatural. Oka said this is because we have acquired unnatural attitudes. He compared morality to teaching a child to write.
Children naturally hold a pen low down near the nib, which cramps their writing.
But later on they ought to be told to hold the pen higher up and loosen their grip, which is how a 160 wpm shorthand expert holds his pen. He does not have to keep moving his hand across the page with every word, as children do. It is the natural way of doing it. When one is made to sit up and hold the pen higher and loosely, at first it seems unnatural, but it is really natural. When they have been resolved with some effort, the natural tendency asserts itself.
