Not only are the sacred beings separated from the profane, but also nothing which either directly or indirectly concerns the profane life should be confused with the religious life. Complete nudity is frequently demanded of the native as a prerequisite to being admitted to participation in the rites;[1035] he is required to strip himself of all his habitual ornaments, even those to which he is the most attached, and from which he separates himself the least willingly because of the protecting virtues he attributes to them.[1036] If he is obliged to decorate himself to play his part in the ritual, this decoration has to be made specially for the occasion; it is a ceremonial costume, a gala dress.[1037] As these ornaments are sacred, owing to the use made of them, he is forbidden to use them in profane affairs; when the ceremony is finished, they are buried or burnt;[1038] the men must even wash themselves in such a way as to carry away with them no trace of the decorations with which they were adorned.[1039] In general, all acts characteristic of the ordinary life are forbidden while those of the religious life are taking place. The act of eating is, of itself, profane; for it takes place every day, it satisfies essentially utilitarian and material needs and it is a part of our ordinary existence.[1040] This is why it is prohibited in religious times. When one totemic group has loaned its churinga to a foreign clan, it is an exceptionally solemn moment when they are brought back and put into the ertnatulunga; all those who take part in the ceremony must fast as long as it lasts, and it lasts a long time.[1041] The same rule is observed during the rites,[1042] of which we shall speak in the next chapter, as well as at certain moments of the initiation.[1043]
