There was much that was hard and cruel about this religion. The idols were made hideous that they might strike terror to the worshipers. Human sacrifices were offered at times to the chief gods. The idols of the natives were much like those of the North American Indians, but the Kanakas are not like the Indians in character. The oppressive tabu was part of the religion, and the penalty for breaking it was death. The word means prohibited, and the system was a set of rules, made by the chiefs and high priests, which forbade certain things. For instance, it was tabu for women to eat with men or enter the men's eating house, or to eat pork, turtles, cocoanuts, bananas and some kinds of fish. There were many tabu periods when "no canoe could be launched, no fire lighted, no tapa beaten or poi pounded, and no sound could be uttered on pain of death, when even the dogs had to be muzzled, and the fowls were shut up in calabashes for twenty-four hours at a time." Besides the religious tabus there were civil ones, which could be imposed at any time at the caprice of king or chiefs, who would often forbid the people to have certain things because they wished to keep them for themselves. One is apt to think that in those early days the natives of these heavenly islands must have been happy and free-living, without laws and doing as they wished, with plenty of fruit and fish to eat; but it was not so at all, for they were obliged to crawl in the dust before their king; they were killed if they even crossed his shadow. As a pleasant contrast to all these grim features, the Hawaiians, like the ancient Israelites, had cities of refuge, of which there were two on the island of Hawaii. Here the murderer was safe from the avenger, the tabu-breaker was secure from the penalty of death, and in time of war, old men and women and children could dwell in peace within these walls. The curious belief in a second soul, or double, and in ghosts, the doctrines of a future state, and the peculiar funeral rites, all of which formed part of the native religion, seem strange to many present-day Christian Hawaiians. In all Polynesia the four great gods were Kane, "father of men and founder of the world,"[5] Kanaloa, his brother, Ku, the cruel one, and Lono, to whom the New Year games were sacred. These four were also the chief deities of Hawaiians.
