It is believed that if a person dies during the ‘Panchak’ period, then at the time of cremation, four or five imitation corpses of ‘Kusha’ [grass]’ or wheat flour are made and cremated along with the dead person on the same pyre and all rituals are carried out for the imitation corpses …., this is said to protect the family from the malefic effect of the ‘Panchak’ phase.
