We learn how to empty our heart through our daily life. 
Whether you want or not, what should come is coming, and what should go is going. 
That's why people say 'a void' . 
Because nothing lasts forever on the earth. 
Thus, if you empty all things you have in heart, you can earn more things…
..I can see infinite space at the closed door, 
and a seed of new life from everything heading for death.
