Developing inner values is much like physical exercise. The more we train our abilities, the stronger they become. The difference is that, unlike the body, when it comes to training the mind, there is no limit to how far we can go.
Do not accept what you hear by report, do not accept tradition, do not accept a statement because it is found in our books, nor because it is in accord with your belief, nor because it is the saying of your teacher.

Fighting for one's freedom, struggling towards being free, is like struggling to be a poet or a good Christian or a good Jew or a good Muslim or good Zen Buddhist.

The Four Reliances. First, rely on the spirit and meaning of the teachings, not on the words; Second, rely on the teachings, not on the personality of the teacher; Third, rely on real wisdom, not superficial interpretation; And fourth, rely on the essence of your pure Wisdom Mind, not on judgmental perceptions.

As you become less attached to the world, you become more humane. As the very purpose of spiritual practice is to help others, you must remain in society.
