§ 101. The radical forms of worship among the Dakota, according to Lynd, are few and simple. One of the most primitive is that of Wocnapi (Wośnapi) or Sacrifice. To every divinity that they worship they make sacrifices. Even upon the most trivial occasions the gods are either thanked or supplicated by sacrifice. The religious idea it carries with it is at the foundation of the every-day life of the Dakota. The wohduze or taboo has its origin there; the wiwaŋyag waćipi or sundance (§§ 141-211) carries with it the same idea; the wakaŋ wohaŋpi or sacred feast (feast of the first-fruits) is a practical embodiment of it; and haŋmdepi or god-seeking of the extreme western tribes is but a form of self-sacrifice. No Dakota in his worship neglects this ceremony. It enters into his religious thoughts at all times, even at the hour of death. The sacrifices made upon recovery from sickness are never composed of anything very valuable, for the poverty of the Indian will not permit this. Usually a small strip of muslin, or a piece of red cloth, a few skins of some animals, or other things of no great use or value are employed. Sometimes a pan or kettle is laid up for a sacrifice. But after a short time, the end for which the sacrifice was made is attained, and it is removed. Those in need of such things as they see offered in sacrifice may take them for their own use, being careful to substitute some other articles. Perhaps the most common forms of sacrifice are those which are made in the hunt. Particular portions of each animal killed are held sacred to the god of the chase or some other deities. If a deer is killed, the head, heart, or some other part of it is sacrificed by the person who has slain it. The part sacrificed differs with different individuals. In ducks and fowls the most common sacrifice is of the wing, though many sacrifice the heart, and a few the head. This custom is called wohduze, and is always constant with individuals, i. e., the same part is always sacrificed. The other wohduze or taboo is connected with the wotawe or armor,[99] and will be described hereafter (§ 125). § 102. _Haŋmdepi or god-seeking._--Haŋmdepi or god-seeking is a form of religion among the Dakotas that points back to a remote antiquity. The meaning of the word, in its common acceptation, appears to be greatly misunderstood by some. Literally, it means only to dream, and is but another form of haŋma; but in its use it is applied almost wholly to the custom of seeking for a dream or revelation, practiced by the Sisitonwan, Ihanktonwanna, and Titonwan (Sioux), and by the Crow, Minnetaree, Assiniboin, and other western Dakota. In this respect it has no reference whatever to the common dreams of sleep, but means simply the form of religion practiced.
