There are certain places in this world which have healing power. Some of them are spatial; others are temporal. Alyosha Karamazov was remembering his mother’s face, praying: that is also a place of healing, even if it is about a face–or rather about a relationship. Remembering it, being in its presence, does not allow you to think bad things. The embrace of my grandma. I cannot judge people while I remember her embrace. A monastery: peace penetrating your bones.
In my experience, all of these places have one feature in common: you are loved.
Preserve the places of regeneration of this world. Which may also mean “become a place of regeneration for others.” Or “love.”
