In remote northern Ethiopia, a lone priest makes an 800-foot climb, barefoot and without ropes, to reach a small church carved out from the side of a mountain.
"Your mind travels to whatever you choose to focus on. If you read a spiritual book, and understand the secret, it brings you joy. If you read and understand the word of God, it tastes as sweet as honey."
The church's previous priests are buried inside. None have died during the climb.
