Kalyāṇa-mittatā (Pali; Skt.: -mitratā) is a Buddhist concept of "spiritual friendship" within Buddhist community life, applicable to both monastic and householder relationships. One involved in such a relationship is known as a "good friend," "virtuous friend," "noble friend" or "admirable friend" (kalyāṇa-mitta, -mitra).
Since early Buddhist history, these relationships have involved spiritual teacher-student dyads as well as communal peer groups. In general, such is a supportive relationship based on shared Buddhist ethical values and the pursuit of enlightenment.
In contemporary Western society, this concept has gained increased currency within the Triratna Buddhist Community (formerly the Friends of the Western Buddhist Order) (UK) and the Spirit Rock Meditation Center (USA).
In the Pali Canon's Upaddha Sutta (SN 45.2), there is a conversation between the Buddha and his disciple Ananda in which Ananda enthusiastically declares, 'This is half of the holy life, lord: admirable friendship, admirable companionship, admirable camaraderie.' The Buddha replies:
The Buddha elaborates that, through such friendships, one develops each of the path factors through seclusion, dispassion and cessation. Further, the Buddha states that through spiritual friendship with the Buddha himself followers have gained release from suffering.
According to Dr. R.L. Soni, canonical discourses state that "companionship with the wise" leads to the following developmental progression: "listening to good advice, rational faith, noble thoughts, clear thinking, self-control, good conduct, conquest of the hindrances, gaining of wisdom and the consequent liberation."
