In the days of stamps and letter writing, C/O read ‘care of’. These days, the same two letters (CO) look a little less innocent, fault of associations with carbon dioxide (CO2), a greenhouse gas that keeps at least a few climate scientists up at night.

But we produce CO2 every time we exhale. And as the teachings of the Great Buddha remind us, “Nirvana is but a breath away.” Sounds close. We might be able to experience a bit of the sublime if we start sending care packages to strangers or loved ones in a protective vessel filled with our breath. This concept explores that possibility. Breathe in. Breathe out. Transcend greed, hatred, and delusion (but make sure to send the packages via USPS).
