No matter what you lost, or how you were hurt, there is no future for you in your painful memories.
The past may have given you awareness, but it is not awareness. The past is real, but it is as ephemeral, and as unreal, and as unreachable, like any other illusion.
Memories are illusions; echoes of the past. Memories can be a form of false consciousness; a place one lives to avoid living.
As your past emerges in your mind, you vanish in the present. If you are not careful, your memories can imprison you. You must stop thinking about what you wish to repair from the past.
You cannot heal memories, you can only heal yourself in the present. All your pain from your past has already served you.
Keep the lessons of your pain, but not the memories of your pain. Let it all go!
