Expulsion
The Bhutanese Vajrayāna tradition employs a wide range of techniques and methods to pacify the world and lead the sentient beings on the path to enlightenment. When the sentient beings are considered unruly and inresponsive to the peaceful teachings, tantric Buddhism uses expedient forces to stop the evil beings from committing negative actions and harming others. The ritual of exorcism using the meditation and visualisation of a wrathful Buddha is a way of chasing away evil forces and other obstacles and misfortunes. The evil forces are vanquished and driven away and an imaginary fence being drawn to stop them from returning. The chief of the evil to be chased, however, is often identified to be one's ego and attachment to self.
