Discipline of Conscience

"It is because we have at the present moment everybody claiming the right of conscience without going through any discipline whatsoever that there is so much untruth being delivered to a bewildered world" - Gandhi

I believe that this sentence has many implications and directions for anyone with the courage to think about it. Do we have an existential right of belief, of personal understanding, or does it come from study, thought, and discipline? But the follow up question is what constitutes enough discipline, or correct discipline? Does all discipline lead towards the same direction? And if so, how do we achieve the discipline?

I think that Gandhi has it spot on here, and I discipline involves personal growth, questioning and understanding. But this goes a step further. Discipline involves knowing that their are limitations to your thoughts, to your understanding, and you might have missed some things. You should be open to those being pointed out to you. The discipline to not retreat to ignorance and close mindedness and to face the fears of mistakes, and muster up the strength of will to question and study with new information in light. To know you know nothing. To know you don't have the answers, and you only make an attempt for good, even though that attempt might be wrong.
I think that would solve the issue of getting carried away with something, or taking something too far.
