There are tomes within occult circles famed for their enormity. The Mahabhairavacaryāvatāra (Skt. The Holy Path of the Great Terror) is such a book. It is believed to have been penned around 1215 by the great Nepalese sadhu Rudracitta (Skt. He whose mind is malignant), a mystic famed for his powerful siddhis and acts of black magic.
Rudracitta founded the Marasāgara Sangha (Skt. The Brotherhood of the Demon Ocean), a death cult that worships an entity identified within the pages of the Mahabhairavacaryāvatāra as Vajrakāla (Skt. The Diamond Black One). The aim of Rudracitta in founding the Marasāgara Sangha is to bring about the dominion of Vajrakāla on this plane of existence.
After the establishment of the Marasāgara Sangha Rudracitta went on an extended retreat lasting for three years, three months and three days. It was during this retreat that he is said to have composed the Mahabhairavacaryāvatāra, a text for summoning various extra-dimensional entities loved by Vajrakāla.
The Marasāgara Sangha fractured after Rudracitta’s death circa 1250 and the Mahabhairavacaryāvatāra faded into relative obscurity.
The next recorded instance of the text resurfacing was in Thailand. In 1574 Śīlarāja, a thudong monk, had a vision of the text and spontaneously composed the short lived Thai version. Śīlarāja studied the text with a view to learning the banishment rituals within but he became corrupted by the promise of power and fell under its seductive sway. Drunk on power he murdered thirty people before being hunted down by the local authorities. The fate of the Thai version of the text is unknown.
In 1856 British historian Alfred Smith discovered a Sanskrit copy of the text in Nagpur. It is not known how he came to know of the texts existence, its location, nor how he came to acquire it. He used it to summon an Inchoate, the first recorded instance of the creature being summoned. It is not recorded how the creature was despatched nor the fate of Smith’s copy of the text.
The next appearance of the Mahabhairavacaryāvatāra is implied but the appearance of an Inchoate in 1971 in the New England town of Starham strongly suggests its presence as this creature is only known to be referred to in Rudracitta’s text.
It is not known if that copy of the Mahabhairavacaryāvatāra was destroyed when Col. Thomas Clarke destroyed the Inchoate and the town of Starham with it.
There are two copies of Mahabhairavacaryāvatāra known to be extant. The first is in the Vatican’s Secret Archives. The second, thought to be in the British Library, is actually in the possession of linguist Dr. Julie Dennett.
