The Drūj is expelled from the dead by the Sag-dīd, or “the look of the dog;” “a four-eyed dog,” or “a white one with yellow ears,” must be brought near the body, and made to look upon the dead, and as soon as he has done so the Drūj hastens back to hell.[191] The Drūj is expelled from the living by a process which is too revolting for description. The ceremonies are accompanied by the constant repetition of spells like the following: “Perish, O fiendish Drūj! Perish, O brood of the fiend! Rush away, O Drūj! Perish away to the regions of the north, never more to give unto death the living world.” The feeling out of which these ceremonies grew was not original with Mazdeism; the Hindū also considered himself in danger while burning the corpse, and he cried aloud, “Away, go away, O Death! injure not our sons and our men.”[192] The Pārsīs, not being able to find a four-eyed dog, interpreted the law to mean a dog with two spots above the eyes, while in practice they are still less particular, and the Sag-dīd may be performed by a house-dog, or by a dog four months old. As birds of prey are fiend-smiters as well as the dog, the devotee may claim their services when there is no dog at hand. The four-eyed dog, which the ceremony originally called for, is doubtless a reproduction of “the four-eyed dogs of the tawny breed of Saramā,” belonging to Yama,[193] which guard the realms of death in Hindū mythology. The identity of the four-eyed dog of the Pārsīs with the dogs of Yama is confirmed by the tradition that the yellow-eared dog watches at the head of the Chinvat bridge, and, as the souls of the faithful pass over, he barks to drive away the fiend who would drag them down to hell. Wherever a corpse is carried, death walks beside it all the way, from the house to the last resting-place, and the fatal presence constantly threatens the living who are near the path-way. DISPOSITION OF THE DEAD. As the centre of contagion is in the corpse, it must be disposed of in such a way that death may not be spread abroad. The old Indo-European customs have in this respect been completely changed by Mazdeism. The corpse was formerly either burned or buried; both of these customs, however, are held to be sacreligious in the Avesta. The elements, fire, earth, and water, are holy, and even during the Indo-Īrānian period they were already so considered, being represented in the Vedas as objects of worship. But this did not prevent the Hindūs from burning their dead, and the dead man was really considered as a traveler to the other world, while the kindly fire was supposed to carry him on flashing pinions to his heavenly abode. The funeral fire, like that of the sacrifice, was the god that goes from earth to heaven, the mediator most friendly to man.
