It’s not that deep
Captain Obvious said “If you forgive anyone’s sins, they are forgiven; if you do not forgive them, they are not forgiven.”
But Paul McCartney made it sound cooler when he sang “Live and let die.”
From Ikkyū:
Every day priests minutely
examine the Dharma
and endlessly chant
complicated sutras.
They should learn
how to read the love letters
sent by the wind and rain,
the snow and moon.
