The eldest son, or a male mourner, or a priest – called the lead cremator or lead mourner – then bathes himself before leading the cremation ceremony. He circumambulates the dry wood pyre with the body, says a eulogy or recites a hymn, places sesame seeds or rice in the dead person's mouth, sprinkles the body and the pyre with ghee (clarified butter), then draws three lines signifying "Yama" (deity of the dead), "Kala" (time, deity of cremation) and the dead. Prior to lighting the pyre, an earthen pot is filled with water, and the lead mourner circles the body with it, before lobbing the pot over his shoulder so it breaks near the head. Once the pyre is ablaze, the lead mourner and the closest relatives may circumambulate the burning pyre one or more times. The ceremony is concluded by the lead cremator, during the ritual, is "kapala kriya", or the ritual of piercing the burning skull with a stave (bamboo fire poker) to make a hole or break it, in order to release the spirit.
