I am of the nature to grow old. There is no way I can escape growing old.
I am of the nature to get sick. There is no way I can escape getting sick.
I am of the nature to die. There is no way I can escape death.
All that is dear to me and everyone I love will change. There is no way I can 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.
