Lovingkindness, an awkward and somewhat quaint term in English, is the translation of the Pali word metta, which means complete and unrestrained friendliness. The Buddha taught that when the mind is at ease, it is friendly, congenial, well-wishing. The mind at ease likes nearly everybody. Even people who, because of who they are or what they do, are very hard to like, the mind at ease accommodates with compassion.
