Upajjhatthana Sutta

A woman or a man, a householder or one gone forth, should often reflect thus:
(1) ‘I am subject to old age; I am not exempt from old age.’
(2) ‘I am subject to illness; I am not exempt from illness.’
(3) ‘I am subject to death; I am not exempt from death.’
(4) ‘I must be parted and separated from everyone and everything dear and agreeable to me.’
(5) ‘I am the owner of my kamma, the heir of my kamma; I have kamma as my origin, kamma as my relative, kamma as my resort; I will be the heir of whatever kamma, good or bad, that I do.
