The name Vajra master originated from a translation of the Tibetan word Acaryas which encompasses very broad and general constituents. This name embodies various concepts of being a Vajra master and categorically represents different Vajra masters: authentic Vajra master, fake Vajra master, mediocre Vajra master, and holy Vajra master. The differences in caliber between them are like night and day. Suppose a Buddhist practitioner can impart common Buddhist ordinances and doctrines, uphold strict precepts, propagate Dharma, and benefit the public and all beings. In that case, this Buddhist practitioner can be a teacher and in Vajrayana, this teacher is called a Vajra master.
