Pāramitā (Sanskrit, Pali: पारमिता) or pāramī (Pāli: पारमी) is a Buddhist term often translated as "perfection". It is described in Buddhist commentaries as a noble character quality generally associated with enlightened beings. Pāramī and pāramitā are both terms in Pali but Pali literature makes greater reference to pāramī, while Mahayana texts generally use the Sanskrit pāramitā.
Maitrī (Sanskrit; Pali: mettā) means benevolence, loving-kindness, friendliness, amity, good will, and active interest in others. It is the first of the four sublime states (Brahmaviharas) and one of the ten pāramīs of the Theravāda school of Buddhism.
The cultivation of benevolence (mettā bhāvanā) is a popular form of Buddhist meditation. It is a part of the four immeasurables in Brahmavihara (divine abidings) meditation. Metta as "compassion meditation" is often practiced in Asia by broadcast chanting, wherein monks chant for the laity.
