The story of your life is written with a pencil, not a pen. And pencils have erasers. You can undo your past by erasing the pencil mark and writing a new story.
The past has a limited memory. The future gets written by the present, not the past. You can change your dark past, into a shining future. You will need to erase the past. Your virtue, and humanity will need to shine. Your past will be forgotten.
Pencils have erasers!
