Mettā
Mettā (Pali) or maitrī (Sanskrit) is benevolence, friendliness, amity, friendship, good will, kindness, close mental union (on same mental wavelength), and active interest in others. It is the first of the four sublime states (Brahmavihāras) and one of the ten pāramīs of the Theravāda school of Buddhism. Mettā is love without the suffering that arises from attachment (known as upādāna).
