Vajrabhairava is a wrathful form of Manjushri and functions as a meditational deity of the Anuttarayoga Classification in Tantric Buddhism. Vajrabhairava is NOT a protector deity and is NOT included in any Buddhist classifications of protectors. As a principal meditational deity Vajrabhairava, belongs to the Vajrabhairava and Yamari class of tantras and specifically arises from the Vajrabhairava Root Tantra (Tib.: jig je tsa gyu). The Vajrabhairava and Yamari Tantras belong to the method (father) classification of Anuttaryoga Tantra.
The practice of Vajrabhairava is common to the three main Sarma Schools of Tibetan Buddhism: Sakya, Kagyu and Gelug. Among the Sakya it is counted as one of the four main tantric deities along with Hevajra, Guhyasamaja and Chakrasamvara (Tib.: gyu de shi). Amongst the various Kagyu Schools the Drigungpa are strong upholders of the practice. In the Gelug School Vajrabhairava is the principal meditational deity taught for Anuttarayoga practice along with the meditational deities Akshobhyavajra Guhyasamaja and Chakrasamvara. There are numerous forms and styles of practice from the very complex with numerous deities to the very concise with a single Heruka form - one face and two arms. From amongst the many different lineages and teachings of Vajrabhairava to enter Tibet it is said that the main ones were those of Rwa Lotsawa and Mal Lotsawa.
Nine Stacked Faces & Nine Circular Faces: There are two different systems for depicting the nine faces of Vajrabhairava. The first system is called  Stacked Faces (zhal tseg) and the second is called  Circular Faces (zhal kor). The first, Stacked Faces is considered the older system and can be found depicted primarily in the paintings and sculpture of the Sakya, Marpa Kagyu, Jonang and Shangpa Kagyu Traditions. The second system of Circular Faces is depicted in the Gelug Tradition. There are occasions where Circular Faced depictions can be found in the Bodong and Ngor Traditions of Sakya. However these instances are rare and isolated to minor or secondary figurative depictions in a larger painting with a central figure and dozens of secondary figures.
Vajrabhairava with nine Stacked Faces is defined by the central face of the deity having a buffalo head with a single wrathful face placed to the right and left sides. Stacked above that are three more wrathful faces. Again above that are three faces. The top level has two wrathful faces at the sides and the middle top face is that of Manjushri, orange in colour, slightly peaceful and slightly wrathful. This orientation or configuration of three levels of three faces is called Stacked Faces.
Vajrabhairava with nine Circular Faces is defined by the central face being that of a buffalo with three additional faces placed to the immediate right side and three more faces placed to the immediate left side. Above the central buffalo face are two more faces one above the other. The orange face of Manjushri is identified as the uppermost face. This orientation is called Circular Faces.
In the 15th and 16th centuries there were a number of dialectic exchanges between teachers of the Sakya and Gelug traditions claiming the orthodoxy of one system over the other. Early examples of paintings and sculpture from both India and Nepal use the Stacked Face system. Early Tibetan paintings can be identified that also depict both forms of Vajrabhairava with examples of minor figures that also depict the deity with the circular faces. Both appear to be old Tibetan iconographic forms with one more dominant than the other.
It was Tsongkapa in the 14th century that popularized the deity Vajrabhairava with Circular Faces as one of the three principal (Anuttarayoga) meditational practices in the Gelug Tradition of Tibetan Buddhism. As a general rule in the study of Buddhist Tantric iconography - any depiction of Vajrabhairava with the faces in a circular orientation means that it most likely belongs to a Gelug iconographic program. Depiction of Vajrabhairava with a stacked face orientation belong to a Sakya, Marpa Kagyu or Jonang iconographic program.
The Three Forms of the Consort: Vetali, the female consort in wrathful aspect embracing Vajrabhairava Sarasvati, the peaceful aspect of the consort Oden Barma (Blazing with Light) the protector aspect of the consort
The words Yama, Yamari, Yamantaka, Bhairava and Vajrabhairava appear frequently in all classes of tantric texts and they can refer to an attendant deity, a protector, or as a worldly god beneath the feet of a Buddhist meditational deity (Skt. ishtadevata) such as Vajrayogini, or Chakrasamvara. In those instances Bhairava represents the various negative emotions to be conquered through meditation. Keeping in mind the similarities in name and form it is important not to confuse the various names, identities, deities and especially the Buddhist Tantric models and systems that each belongs and to properly understand each in its own place.
