The Vajrasattva Drubchö is a seven-day ceremony based on the Minling Dorsem or Mindrolling Vajrasattva ritual. Minling Dorsem is part of the Vajrasattva cycle of teachings discovered by Chögyal Terdag Lingpa. The Drubchö is held every year for seven days beginning on the 10th day of the first lunar month. This grand ceremony is performed to purify the negativities of all sentient beings, particularly of the deceased. On the 15th day of the first lunar month (the sixth day of the Drubchö), His Holiness Mindrolling Trichen, along with the entire sangha, performs a special ceremony for those who have died within the previous year.
