All formations are transient; all formations are subject to suffering; all things are without a self.

Therefore, whatever there be of form, of feeling, perception, mental formations, or consciousness, whether past, present, or future, one’s own or external, gross or subtle, lofty or low, far or near, one should understand according to reality and true wisdom: ‘This does not belong to me; this am I not; this is not my Self.’
- Anguttara Nikaya and Samyutta Nikaya
