I first saw ema at the Meiji Shrine in Tokyo. This is another place, possibly in Kyoto, but the idea is the same.
For a donation of a few yen, one takes a wooden tablet and writes a wish, hanging it with the others around a sacred tree.
In the morning, all of these wishes in languages from around the world are offered by the priests.
I read a few, and in the languages I can read, I see hopes of peace and love, prosperity and happiness, health and friendship.
I think, around the world, we all want the same things deep down, and any disagreements are no more than ice cream preferences.
