The past is a storehouse of all the things that have been done.

The transitoriness of life does not annihilate what has happened.

On the contrary, what has happened in stored forever in the past. 

Something done can never be undone. (Viktor Frankl)

The past is “stored” and this is clearly why stories are so powerful. They can recreate things experienced in the past with the possibility of transforming them in the present.
