Sharing wishes with strangers makes a powerful emotional statement.

You write your wishes/prayers on the Lantern then float it in a body of water. I’ve done various volunteer activities with this Buddhist Temple.  I don’t attend as much as I used to but I still get together with my Japanese friends for Buddhist services, chanting and meditation.
