The Bhumpa, or Ritual Vase, is an important ceremonial item used for holding holy water that has been blessed by the Guru. The holy water is believed to remove negativity and to chase away evil spirits, and it is sprinkled or poured to purify persons, places or objects. Bhumpas are widely used by Gurus in many types of ceremonies, from elaborate purification rituals for new houses, monuments and holy sites, to simple blessings for disciples meant to purify and protect them from harmful forces. Bhumpas may also be used by practitioners to make water offerings; in such cases the water is regarded as pure nectar.
During the performance of some Tantric rituals two matching Bhumpas are used. These are called the "chief" or "principal" vase, and the "action" or "working" vase. The principal vase is filled with holy water and remains upon the altar in the monastery or temple, while the action vase is used for the actual pouring of water for purification during the various stages of the ritual.
