The Buddha's Five Remembrances
I am of the nature to grow old.
There is no way to escape growing old.
I am of the nature to have ill health.
There is no way to escape ill health.
I am of the nature to die.
There is no way to escape death.
All that is dear to me and everyone I love
are of the nature to change. There is no
way to escape being separated from them.
My actions are my only true belongings.
I cannot escape the consequences of my actions.
My actions are the ground upon which I stand.
- Anguttara Nikaya 5.57 - Translation by Thich Nhat Hanh
The Five Remembrances are closely related to the Four Sights.
