“What was lost was lost. There was no retrieving it, however you schemed, no returning to how things were, no going back.”

“I can't go back because I lost all my Soul Reaper powers! - Rukia
You lost your powers? What are they, socks? - Ichigo”

“It shocks me how I wish for… what is lost and cannot come back.”

“They knew that if they let each other go they were lost, but if they went on holding each other they were also lost.”

“We come from nothing, we are going back to nothing-In the end what have we lost? Nothing!”

“There is a point at which everything becomes simple and there is no longer any question of choice, because all you have staked will be lost if you look back. Life's point of no return.”

“You get lost out of a desire to be lost. But in the place called lost strange things are found…”

“What comes, will go.
What is found, will be lost.
But what you are is beyond coming and going and
beyond description. You are this:
The timeless-time”

“Forgiveness has its comforts, but it can never give you back what you've lost.”

“What you’re really doing is trying to win back what you’ve lost by going all in. It’s shitty poker, and even worse as a battle strategy.”
