It is the mark of an educated mind to be able to entertain a thought without accepting it. - Aristotle
Meditation brings wisdom; lack of meditation leaves ignorance. Know well what leads you forward and what hold you back, and choose the path that leads to wisdom. - Buddha
When an ordinary man attains knowledge, he is a sage; when a sage attains understanding, he is an ordinary man. - Zen proverb
