Another important ritual occasion in Tibetan Buddhism is that of mortuary rituals which are supposed to assure that one has a positive rebirth and a good spiritual path in the future. Of central importance to Tibetan Buddhist "Ars moriendi" is the idea of the bardo (Sanskrit: "antarābhava"), the intermediate or liminal state between life and death. Rituals and the readings of texts such as the "Bardo Thodol" are done to ensure that the dying person can navigate this intermediate state skillfully. Cremation and sky burial are traditionally the main funeral rites used to dispose of the body.
