Here is the Karaniya Metta sutta (the Buddha's words on loving-kindness) in Pali (an ancient Indian language for which I'm afraid I've lost some of the diacritics), followed by an English translation by Ratnaprabha. This is a version for easy printing - you can also read and listen along here!

Listen to Natalie's talk about the sutta, and here's Joe's chanting of the Pali as a separate audio post.
