Aro is a lineage within the Nyingma tradition of Tibetan Buddhism. It has several unusual characteristics. The terma on which it is based teaches all Buddhist topics from point of view of Dzogchen, and so is characterized by uncommon simplicity. The lineage is entirely non-monastic (Ngagpa), and so emphasizes householder practice and non-celibate ordination. All its contemporary teachers are ethnically non-Tibetan.
