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.

The term appears in Buddhist texts as an important concept and practice. Buswell and Lopez, as well as Harvey, translate metta as "loving-kindness". In Buddhist belief, this is a Brahmavihara (divine abode) or an immeasurable that leads to a meditative state by being a counter to ill-will. It removes clinging to negative states of mind, by cultivating kindness unto all beings. The "far enemy" of metta is hate or ill-will, a mind-state in obvious opposition. The "near enemy" (quality which superficially resembles metta but is in fact more subtly in opposition to it), is attachment (greed): here too one likes experiencing a virtue, but for the wrong reason. Mettā meditation, or often "loving-kindness meditation", is the practice concerned with the cultivation of mettā, i.e.
