Brahmaviharas Talks

The brahmavihārā (sublime attitudes, lit. "abodes of Brahma") is a series of four Buddhist virtues and the meditation practices made to cultivate them. They are also known as the four immeasurables (Pāli: appamaññā) or four infinite minds (Chinese: 四無量心). The brahmavihārā are:

loving-kindness or benevolence (mettā) compassion (karuṇā) empathetic joy (muditā) equanimity (upekkhā)

According to the Metta Sutta, cultivation of the four immeasurables has the power to cause the practitioner to be reborn into a "Brahma realm" (Pāli: Brahmaloka).
