Like all Buddhism, Vajrayana Buddhism is based on the idea that"life is suffering." In other words, a basic component of existing is the fact that the being who is existing will eventually suffer. The only way to escape this suffering is to escape from the cycle of rebirths and cease existing altogether.
This fits well with the predisposition in gothic literature of focusing on suffering as an important part of who we are and how we experience the universe. Specifically, many gothic writers focus on suffering as a constant consequence of being alive.
In Tibetan Buddhism death is symbolized with the use of bones and skeletons to make musical instruments . like from the thigh bone a trumpet, even skulls being carved into skull caps. Dancers would also be painted to represent skeletons. They do this so that they are reminded of death, and the fact that life is not eternal. And another reason that they confront death is that at a point in time they will have to confront evil spirits and then they must commit the ultimate sacrifice to achieve enlightenment.
Ancient Buddhist Masters were believed to tame powerful demons, they were able to bind them to do good and to protect religious followers with an unbreakable oath. These Buddhist masters were named Dharmapals and are considered to act benevolently, even though those wrathful beings enjoy receiving offerings at many temples and altars spread through Tibet. Some offerings are made of artificial meat and blood made of vegetable ingredients. But there are practicioners who use real meat and blood for these offerings. Many wealthy people have an individual room devoted to the worship of these Masters, they would be complete shrines decorated with weaponry and stuffed animals with extreme wrathful expressions. Many of the Monasteries have an underground hall for worship. The reason being these halls could be kept dark and ideal for the chanting rendered a sort cacophonous sound that is deep and foreboding .The highest Buddhist Master the Pehar resides in a palace completely decorated to give one the feeling that when someone walks through the halls it feels as they are walking through hell because of the doorknobs represent heads of demons and the walls themselves are decorated with flayed skin.
Unique to Buddhism is the belief that emotions can eliminate and counteract other emotions. This is considered to be difficult and very dangerous feat to attempt, it is however also considered the fastest way to achieve enlightenment. Many Buddhist practices are emotionally potent and very sensual, sexual intercourse is used to help achieve enlightenment. In other rituals they must confront death in a ritual, or they confront wrathful emanations of buddhas who reflect one's deep loathing hatred and unease. Others use alcohol drunken from a skull-cup.
In Vajrayana Buddhism, there is no predefined difference between "good magic" and "bad magic.". One of Tibet's greatest heroes is a sorcerer , he used his magic to harm others. When he found he no longer gained satisfaction in destroying his enemies and turned to Buddhism. Even an advanced Vajrayana Buddhist master has access to secret ceremonies which will enable them take a life. These ceremonies are rarely used except in the rare cases when it is considered an compassionate. Especially when someone has accumulated so much bad Karma by their horrible deeds that they have done. However, there are some Buddhist masters who slip and start using their powers for selfish purposes.
Westerners have identified what they define as their concept of Vampires are. The Sri, is an invisible malevolent spirit, created from bad karma this has devoured the life force of the living. They are also considered to blame when there is an unexplained loss of vitality.
Could this reflect on the Fury, Rakshasa, giant cat-people from another nearby world who can change form and like to drink human blood and devour human flesh. Rakshasa are like vampires in that they are more powerful than humans, can change shapes and prey on humans for nourishment.
Vampires found in gothic fiction, the closest analogy from Tibetan myth would be that of the Düd the Tormented. These are people who would have died, under natural circumstances, but they were kept alive by invisible, malevolent düd entities who desire to feed on their suffering.
Vajrayana Buddhism seems to be made up of evil, licentious, demon-worshippers. Death and suffering are used as symbolism, and not to encourage death and suffering, but to acknowledge death and suffering and to deal with it more effectively. Buddhism practitioners who have dangerous magical power simply acknowledge that the world is a dangerous place and that even they, Buddhist Masters are tempted to use their skills for malevolent deeds. When Vajrayana Buddhists say that "life is suffering" it is not meant to make people suffer more, but to help steer them toward the path of suffering less.
