Describing his awakening, the Buddha said: “Coming to be, coming to be! Ceasing to be, ceasing to be! At that thought, monks, there arose in me a vision of things not before called to mind. Knowledge arose; such is form, such is the coming to be of form, such is its passing away. Recognition arose; such is its coming to be, such is its passing away. And the state of abiding in the understanding of arising and passing away; that too arose.”
- Samyutta Nikaya
