There are, O monks, these four lights. What four? The light of the moon, the light of the sun, the light of fire, and the light of wisdom. Of these four lights, the light of wisdom is supreme.
Doubt everything. Find your own light.
What you think you become.
Awake. Be the witness of your thoughts. You are what observes, not what you observe.
He is able who think he is able.
He who slings mud loses ground.
