"There are three principles in a man's being and life, the principle of thought, the principle of speech, and the principle of action. The origin of all conflict between me and my fellow-men is that I do not say what I mean and I don't do what I say"

This quote by Martin Buber highlights the three foundational elements of a person's existence: their ideas, their speech, and their actions. According to Buber, conflicts develop when an individual's words and actions do not align with their thoughts - essentially when they are not honest or genuine. The quote recommends that being clear and sincere in both speech and action is necessary for harmonious relationships with others.
