Heyoka
The heyoka is a type of sacred clown shaman in the culture of the Sioux of the Great Plains of North America. The heyoka is a contrarian, jester, and satirist, who speaks, moves and reacts in an opposite fashion to the people around them.
Only those having visions of the thunder beings of the west, the Wakíŋyaŋ, and who are recognized as such by the community, can take on the ceremonial role of the heyoka.
Social role
The Heyókȟa is thought of as being in charge of above and below, or are more in charge of the dead, instead of the living. This manifests by their not always doing everything like the others. For example, if food is scarce, a heyókȟa may sit around and complain about how full he is; during a baking hot heat wave, a heyókȟa might shiver with cold and put on gloves and cover himself with a thick blanket. Similarly, when it is freezing he might wander around naked, complaining that it is too hot. A unique example is the famous heyókȟa sacred clown called "the Straighten-Outer":The heyókȟa symbolizes and portrays many aspects of the sacred beings, the Wakíŋyaŋ.
His satire presents important questions by fooling around. They ask difficult questions, and say things others are too afraid to say. Their behavior poses questions, as do Zen koans. By reading between the lines, the audience is able to think about things not usually thought about, or to look at things differently.
Principally, the heyókȟa functions as a mirror and a teacher, using extreme behaviors to mirror others, and forcing them to examine their own doubts, fears, hatreds, and weaknesses. Heyókȟa have the power to heal emotional pain; such power comes from the experience of shame—they sing of shameful events in their lives, beg for food, and live as clowns. They provoke laughter in distressing situations of despair, and provoke fear and chaos when people feel complacent and overly secure, to keep them from taking themselves too seriously or believing they are more powerful than they are.
In addition, sacred clowns serve an important role in shaping tribal codes. Unbound by societal constraints, heyókȟa are able to violate cultural taboos freely and thus critique established customs.
By questioning these norms and taboos, they help to define the accepted boundaries, rules, and societal guidelines for ethical and moral behavior. They are the only ones who can ask "Why?" about sensitive topics; they use satire to question the specialists and carriers of sacred knowledge or those in positions of power and authority.
