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.
The rites of this physical worship, again, were wholly symbolic, and the Indian no more worshiped the Sun than the Christian adores the Cross. The Sun and the Earth, by an obvious parable, holding scarcely more of poetic metaphor than of scientific truth, were in his view the parents of all organic life. From the Sun, as the universal father, proceeds the quickening principle in nature, and in the patient and fruitful womb of our mother, the Earth, are hidden embryos of plants and men. Therefore our reverence and love for them was really an imaginative extension of our love for our immediate parents, and with this sentiment of filial piety was joined a willingness to appeal to them, as to a father, for such good gifts as we may desire. This is the material or physical prayer.
The elements and majestic forces in nature, Lightning, Wind, Water, Fire, and Frost, were regarded with awe as spiritual powers, but always secondary and intermediate in character. We believed that the spirit pervades all creation and that every creature possesses a soul in some degree, though not necessarily a soul conscious of itself. The tree, the waterfall, the grizzly bear, each is an embodied Force, and as such an object of reverence.
The Indian loved to come into sympathy and spiritual communion with his brothers of the animal kingdom, whose inarticulate souls had for him something of the sinless purity that we attribute to the innocent and irresponsible child. He had faith in their instincts, as in a mysterious wisdom given from above; and while he humbly accepted the supposedly voluntary sacrifice of their bodies to preserve his own, he paid homage to their spirits in prescribed prayers and offerings.
In every religion there is an element of the supernatural, varying with the influence of pure reason over its devotees. The Indian was a logical and clear thinker upon matters within the scope of his understanding, but he had not yet charted the vast field of nature or expressed her wonders in terms of science. With his limited knowledge of cause and effect, he saw miracles on every hand,—the miracle of life in seed and egg, the miracle of death in lightning flash and in the swelling deep! Nothing of the marvelous could astonish him; as that a beast should speak, or the sun stand still. The virgin birth would appear scarcely more miraculous than is the birth of every child that comes into the world, or the miracle of the loaves and fishes excite more wonder than the harvest that springs from a single ear of corn.
Who may condemn his superstition? Surely not the devout Catholic, or even Protestant missionary, who teaches Bible miracles as literal fact! The logical man must either deny all miracles or none, and our American Indian myths and hero stories are perhaps, in themselves, quite as credible as those of the Hebrews of old. If we are of the modern type of mind, that sees in natural law a majesty and grandeur far more impressive than any solitary infraction of it could possibly be, let us not forget that, after all, science has not explained everything. We have still to face the ultimate miracle,—the origin and principle of life! Here is the supreme mystery that is the essence of worship, without which there can be no religion, and in the presence of this mystery our attitude cannot be very unlike that of the natural philosopher, who beholds with awe the Divine in all creation.
