Taboos may be violated unconsciously, and tribal laws may be transgressed sometimes intentionally, sometimes by accident. The resulting guilt must be removed, if the offender or the community is not to incur the wrath of the affronted Powers. Sin, like holiness, has this peculiar property that it can be communicated by contact. Savage morality does not always rise above the confusion between the physical and the mental. Evil qualities such as uncleanness can be transferred from persons to things, just as from things to persons. Pains and diseases can be extracted from the sufferer, and magically sent into animals or objects which can be driven away or destroyed; and moral evil can be similarly removed. When an Atkhan of the Aleutian Islands had committed a serious offence and desired to unburden himself, he chose a time when the sun was clear, picked up certain weeds, and carried them about his person. After they were thus sufficiently impregnated by contact {205} with him, he laid them down, called the sun to witness, cast his sins upon them, and threw them into the fire. The consuming flame burned away his guilt. The Peruvian made his confession to the sun, and then bathed in an adjoining river. There he rid himself of his iniquity, saying "O thou river, receive the sins I have this day confessed to the sun, carry them down to the sea, and let them never more appear." The oldest and the most recent rituals repeat the same idea in various forms. In one of the Vedic ceremonials of sacrifice, the sacrificer and his wife towards the close bathed and washed each other's backs. Then having wrapped themselves in fresh garments, they stepped forth, and we read: "Even as a snake casts its skin, so does he cast away all his sin. There is in him not so much sin as there is in a toothless child." Water was likewise employed in Babylonia, where the incantation ran, "I have washed my hands, I have cleansed my body with pure spring water which is in the town of Eridu. All evil, all that is not good, in my body, my flesh, my limbs, begone!" Or, "By the wisdom of thy holy name let the sin and the ban which were created for man's misery be removed, destroyed, and driven away."
