Sejiki is a traditional Japanese Zen Buddhist ceremony for the spirits of departed ones. This powerful ceremony summons forth all restless spirits and pacifies agitation and violence within and without.
Shakyamuni Buddha made a vow that he would continue to sit in meditation until he either died or found the truth. On the morning of the seventh day of his meditation, he experienced enlightenment. This ceremony commemorates that moment. It includes chanting accompanied by a drum during a circumambulation of the Buddha Hall.
