Discipline does not mean suppression and control, nor is it adjustment to a pattern or ideology. It means a mind that sees 'what is' and learns from 'what was'.
But the Church cannot be, in any political sense, either conservative or liberal, or revolutionary. Conservatism is too often conservation of the wrong things: liberalism a relaxation of discipline; revolution a denial of the permanent things.
Mind you, there is no value in learning. You are all mistaken in learning. The only value of knowledge is in the strengthening, the disciplining, of the mind.
Self-discipline, although difficult, and not always easy while combating
negative emotions, should be a defensive measure. At least we will be able to prevent the advent of negative conduct dominated by negative emotion. That is 'shila', or moral ethics. Once we develop this by familiarizing ourselves with it, along with mindfulness and conscientiousness, eventually that pattern and way of life will become a part of our own life.
No doubt it is an evil to be bound by laws, but it is necessary at the immature stage to be guided by rules; in other words, as the Master used to say that the sapling must be hedged round, and so on.
