Sikh beliefs about death
Guru Nanak taught that all people are subject to the transmigration of souls, and that release comes through meditation on the divine name. The soul progresses through births until it reaches mukti, liberation, and union with God.
Sikh teaching frames death plainly: whoever is born shall die and depart, and all shall take their turn. Death is described as the name of forgetting God. The death of a gurmukh, one who follows the Guru’s word in thought and action, results in union with God.
Because the soul continues and the body is only its vessel, the rite is not concerned with preserving the body, and no monument is raised at the place of cremation.
Sikh funeral ceremonies
The Sikh Rehat Maryada, the Sikh code of conduct, sets out the funeral ceremonies in its Article XIX. There is no ordained priesthood in Sikhism; what the code requires of every rite is the recitation of Gurbani and the performing of Ardas.
Cremation is directed at every age. There is no restriction on the time of day, and no auspicious hour to wait for, so families often want the earliest slot available. In the UK, the crematorium takes the place of the open pyre, and the closest relation performs the committal in place of lighting it.
