Lets pretend for a momant that we didnt have aplications built into our computing softwear that determined when we had made a mistake. What would that be like. Would we even notice hour errors. Would it effect the way we communicate and interact with our world?
Would we create a lot of problems for ourselves?
Spell check is a discipline meant to identify inconsistencies and mistakes. It is quite different than auto-correct which allows us to keep typing despite making a mistake. Spell check simply says this is a mistake, then you need to go back and fix it.
Discipline is much like this. We often think of discipline as being constrictive or closing us off in some way. Freedom is a concept that we so cherish that discipline seems antithetical to it. I can do whatever I want. This is the way I want to do it. I don't need to follow the rules.
Of course that is fine, hopefully you will discover your own discipline for improving and breaking through resistance. Regardless, you need discipline to improve, otherwise you will simply be typing gibberish and everyone will dismiss you no matter how important the point you are trying to make.
Discipline allows us to progress, it fosters growth. It points out our flawed action and gross ignorance. It gives your direct feedback right after you do something. If your practice is going to be carried off your meditation seat and change your life, it is discipline that is going to be your vehicle. Committing and then subsequently failing is better than never committing at all.
Commitment carries you forward. Never commit and you'll never know when you have gone astray.
Your discipline doesn't need to prescribe every action you take during the day. The simplest discipline you can have is to do no harm, cultivate positive qualities and train your mind.
Eschew discipline and you will not accomplish your own aims, never mind the aims of others.
