consecration ritual for conferring Acharya status
In esoteric Buddhism (Shingon, Tendai), a formal abhiṣeka ceremony that authorizes a practitioner as an ācārya (阿闍梨), a qualified teacher. Highly technical and domain-specific.
See also: 阿闍梨
Only monks who have undergone the denbō kanjō ritual can transmit the secret teachings of esoteric Buddhism.
阿闍梨 is the title of a master or teacher in esoteric Buddhism; 伝法灌頂 is the specific consecration ritual that confers this status.
From 伝法 (denbō, 'transmission of the Dharma') + 灌頂 (kanjō, 'abhiṣeka, anointment'). The term is a direct borrowing of the esoteric Buddhist concept of abhiṣeka for dharma transmission.
