The kapala is one of the traditional ritual items used by tantric practitioners. It is not to be used unless one has received higher tantric initiations or has the permission of one’s Guru to use it.
Representing a human skull cup, the kapala is an aid to our Dharma practice as it remind us of what we are supposed to visualise during our prayers and meditations.
Offering a kapala to one’s Guru is excellent as it will be used during prayers and rituals. Through this act, we create the merits to receive such initiations in the future; and to do these practices to benefit ourselves and others.
