On day 4 of the meditation retreat I gave a note to my zendo neighbor, thanking her for putting up with my endless fidgeting and letting her know that her stillness inspired me.
In the closing circle, she shared how on her most difficult day, she got a small note from someone which totally upended her perspective, allowing her to integrate what she needed from her struggle and find a state of deep peace.
We can never know what even the smallest act of kindness will mean to someone else.
