Our Great Buddha has shown 5 facts a layman, a laywoman and a monk should contemplate often.
1) “I have a decaying nature. I’m not beyond attaining old age.”
2) “I have the nature of catching illness. I’m not beyond disease & suffering.”
3) “I have a dying nature. I’m not beyond death.”
4) “I have to leave all that is near and dear to me one day.”
5) “I belong to karma; I inherit karma; the reason behind my happiness & sorrow is karma; I’m related to karma and I take refuge in karma.”
