Significant among the tools used by shamans in the Upper Amazon are piedras, or piedras encantadas, magic stones, sometimes called just encantos, charms; such stones are called inkantos by the Machiguenga and Shipibo. My teacher doña María Tuesta told me that her father was a tabaquero who kept two magic stones, one male and one female, in a jar filled with a mixture of tobacco and water. When doña María was about eight years old, while her father still lived with the family, she saw him work with the stones twice. She could see the spirits of the stones: they both had very dark skin and long black hair. The male spirit of the stone had dark red eyes like huayruro seeds. His mouth was painted red, the color of brujería, sorcery — magia roja, red magic, the worst kind. He could stick his tongue out all the way to his chest, as is typical of sorcerers; his flema, magical phlegm, was filled with scorpions, snakes, and toads.
In addition, doña María, in the dream journey that constituted her coronación as a prayer healer, dreamed that she passed by a stream in which piedritas, magical stones of all kinds, large and small, were singing to her: “Welcome, welcome, maestra, doctora.” Doña María counted such magic stones among her animal protectors, since the imanes, spirits, of the stones became black boas, yellow boas, condors, and macaws in order to protect her.
Magic stones may — but need not be — striking in appearance: color, shape, and texture may indicate that a stone is, in fact, encantada. The stone may be shaped like a person or animal, like a snake or a jaguar claw, or have an unusual color, or be visually attractive, or just be rare. The stone may turn up in an unusual place or behave oddly; among the Aguaruna, a magic stone is often found in the stomach or crop of an animal as it is being cleaned. The stone may speak to the shaman, or the spirit of the stone may appear in the shaman’s dreams, or in an ayahuasca vision. Cocama shaman don Juan Curico says that encantos are stones that with time have taken the shape of jungle animals or human body parts. He himself has stones in the shape of a snail, the head of an anaconda, the head of a crocodile, a human hand and head.
Crystals particularly are prized; they are, says one mestizo shaman, luz solidificada, solidified light, with a celestial origin. Ordinary piedra pedernal, flint — “like a crystal, but black,” doña María explained to me — may be a powerful magic stone, perhaps in part because it is not native to the Amazon. Such stones come from Lima, I was told; they are about three inches long. If you put the stone in a glass jar of water, and then drink the water, the stone takes away shame, sorrow, anxiety.
The doctrine of signatures applies to stones as well as to plants. Don Francisco Montes Shuña says that a shaman can tell what stones have power, and what power they have, by looking at their shape and color. A stone of white marble can be an arcana, protection, because it purifies, cleanses, and protects the body; a red stone can nourish the blood; translucent crystals give vision and clarity. A stone in the shape of a human hand can take away pain from the body part on which it is placed.
Magic stones will stick for several hours to the place on the body where sorcery has struck, suck out the harm — the dart, the insect, the scorpion, the phlegmosity — and then drop off. Stones can also be used to rub the place where the sickness is located, to loosen the intrusive pathogenic object, so that the shaman can suck it out from the suffering flesh.
Just as the shaman drinks the plants in order to master them, the shaman drinks the magic stones. The shaman leaves the stones in water for a day, observing la dieta, blowing tobacco smoke over them, telling the stone what the shaman wants to know, and finally drinking the water. The spirit of the stone will then appear in a dream and teach the shaman what the shaman seeks. The spirit of the stone can also be seen when drinking ayahuasca; the stones can also be kept in a tobacco infusion, and the tobacco drunk. “It is something admirable,” says don Juan Curico, “to share the wisdom of millions-year-old beings.”
Beliefs about magic stones are widespread in the Upper Amazon. Among the Waiwai, a magic stone, called ñukwa, appears in the mouth of the apprentice shaman during a dream; holding the stone in his mouth, the apprentice learns to sing the magic songs. Similarly, Warao shamans acquire magic stones which descend into their mouths during dreams. Among the Aguaruna, magic stones are generally used for a variety of purposes — hunting, seduction, planting, warfare. These stones have souls, and can assume human form in dreams; they can drink blood, eat souls, and run away if not properly fed. Rock crystals among the Desana are invested with complex cosmological and sexual symbolism. The stones are fed on tobacco, and stored in water infusions of tobacco; these nicotine-rich infusions are drunk in order to communicate with the spirits of the stones.
Yagua shamans keep two kinds of magic stones — small stones called soul-stones or invisible stones, which are kept safe in the stomach; and visible stones, which are kept in a bag hung around the neck. No shaman ever shows these visible stones, saying that they would then lose their power. Blowing tobacco smoke on these stones increases their size a hundredfold. When small, they may be used as weapons, just like darts; when enlarged with tobacco smoke, they became a barrier of protection. Shamans can also keep pieces of glass, called transparent stones, in their stomach, which they can regurgitate and place in the beer gourds of their victims; when swallowed, the glass cuts up the body from the inside.
The Machigengua apprentice receives stones from an invisible celestial being who appears in the apprentice’s ayahuasca vision. The stones must be fed regularly with tobacco smoke; when they are thus nourished, they turn into jaguars. Machigengua shamans acquire these stones — light-colored or transparent, especially quartz crystals — during initiation or from the shaman’s father or other close relative. These stones are considered the body, or residence, or material manifestation of the spirits. The shaman carries the stones in a small bag and feeds the stones tobacco daily; if the shaman fails to do so, the spirits will leave the stones, and the shaman will die. Canelos Quichua believe that the spirits in their magic stones are those of dead shamans. If you gently blow on such a stone, you will see condensation appear on its surface; this shows that the stone “has breath,” that it is a powerful shaman.
