“Within the extent of your knowledge, you are right.”

“Whatever lessens suffering in yourself and others, that is right. Whatever increases suffering, that is wrong. The answer is within you. When you are free of pride and prejudice, when you are calm and attentive, a light will shine within you. Through meditation and through being mindful you will find your own knowledge of rightness. You will be your own light.”

“Plan to the extent that feels right to you at a particular time in your life, but always be open to serendipity.”

“Real knowledge is to know the extent of one's ignorance.”

“Keep the extent of your abilities unknown.The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honored at all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.”

“Live and act within the limit of your knowledge and keep expanding it to the limit of your life.”
