Your eyes will deceive you, your ears will deceive you, your experience will deceive you, your imagination will also deceive you, but mathematics will not.
If memory is a city
Then that city must look new every day.
Because your memory can also deceive you.
Those love and hate, sweetness and bitterness, struggle and hope, bright sunshine and dark abyss, have always been in that city of memory.
Purpose: Get rid of the memories of the past and usher in a new life. No one needs to be defined.
