Every one makes his feast as he thinks best, to please the Great Spirit, who has the care of all beings created. Others believe in two Spirits, one good and one bad, and make feasts for the Bad Spirit, to keep him quiet. They think that if they can make peace with him, the Good Spirit will not hurt them. For my part I am of the opinion, that so far as we have reason, we have a right to use it in determining what is right or wrong, and we should always pursue that path which we believe to be right, believing that ‘whatsoever is, is right.’
