“My religion is to live – and die – without regret.”
Milarepa
There are things which I wish I’d done, and lots of others which I wish I hadn’t, but regret really arises not from the incidents themselves, but from not learning from them.
Everyone makes mistakes, even terrible ones that can’t be forgotten.
But if we squeeze every ounce of wisdom out of these experiences (and maybe it’s precisely these experiences that are particularily rich in wisdom) then we have no reason for regret because, in so doing, we turn them into a source of enrichment.
