When he returned to the camp, he must remain at a distance until he had again entered the vapor-bath and prepared himself for intercourse with his fellows. Of the vision or sign vouchsafed to him he did not speak, unless it had included some commission which must be publicly fulfilled. Sometimes an old man, standing upon the brink of eternity, might reveal to a chosen few the oracle of his long-past youth. The native American has been generally despised by his white conquerors for his poverty and simplicity. They forget, perhaps, that his religion forbade the accumulation of wealth and the enjoyment of luxury. To him, as to other single-minded men in every age and race, from Diogenes to the brothers of Saint Francis, from the Montanists to the Shakers, the love of possessions has appeared a snare, and the burdens of a complex society a source of needless peril and temptation. Furthermore, it was the rule of his life to share the fruits of his skill and success with his less fortunate brothers. Thus he kept his spirit free from the clog of pride, cupidity, or envy, and carried out, as he believed, the divine decree--a matter profoundly important to him. It was not, then, wholly from ignorance or improvidence that he failed to establish permanent towns and to develop a material civilization. To the untutored sage, the concentration of population was the prolific mother of all evils, moral no less than physical. He argued that food is good, while surfeit kills; that love is good, but lust destroys; and not less dreaded than the pestilence following upon crowded and unsanitary dwellings was the loss of spiritual power inseparable from too close contact with one’s fellow-men. All who have lived much out of doors know that there is a magnetic and nervous force that accumulates in solitude and that is quickly dissipated by life in a crowd; and even his enemies have recognized the fact that for a certain innate power and self-poise, wholly independent of circumstances, the American Indian is unsurpassed among men. The red man divided mind into two parts,--the spiritual mind and the physical mind. The first is pure spirit, concerned only with the essence of things, and it was this he sought to strengthen by spiritual prayer, during which the body is subdued by fasting and hardship. In this type of prayer there was no beseeching of favor or help. All matters of personal or selfish concern, as success in hunting or warfare, relief from sickness, or the sparing of a beloved life, were definitely relegated to the plane of the lower or material mind, and all ceremonies, charms, or incantations designed to secure a benefit or to avert a danger, were recognized as emanating from the physical self.
