If you have the insight of non-self, if you have the insight of impermanence, you should make that insight into a concentration that you keep alive throughout the day. Then what you say, what you think, and what you do will then be in the light of that wisdom and you will avoid making mistakes and creating suffering.
Nhat HanhA look filled with understanding, an accepting smile, a loving word, a meal shared in warmth and awareness are the things which create happiness in the present moment. By nourishing awareness in the present moment, you can avoid causing suffering to yourself and those around you. The way you look at others, your smile, and your small acts of caring can create happiness. True happiness does not depend on wealth or fame.
