A ritual may be performed on specific occasions, or at the discretion of individuals or communities. It may be performed by a single individual, by a group, or by the entire community; in arbitrary places, or in places especially reserved for it; either in public, in private, or before specific people. A ritual may be restricted to a certain subset of the community, and may enable or underscore the passage between religious or social states.

The purposes of rituals are varied; they include compliance with religious obligations or ideals, satisfaction of spiritual or emotional needs of the practitioners, strengthening of social bonds, demonstration of respect or submission, stating one's affiliation, obtaining social acceptance or approval for some event — or, sometimes, just for the pleasure of the ritual itself.

Rituals of various kinds are a feature of almost all known human societies, past or present. They include not only the various worship rites and sacraments of organized religions and cults, but also the rites of passage of certain societies, oaths of allegiance, coronations, and presidential inaugurations, marriages and funerals, school "rush" traditions and graduations, club meetings, sports events, Halloween parties, veteran parades, Christmas shopping and more. Many activities that are ostensibly performed for concrete purposes, such as jury trials, execution of criminals, and scientific symposia, are loaded with purely symbolic actions prescribed by regulations or tradition, and thus partly ritualistic in nature. Even common actions like hand-shaking and saying hello are rituals.

Ritual actions

Due to their symbolic nature, there are hardly any limits to the kind of actions that may be incorporated in a ritual. The rites of past and present societies have typically involved special gestures and words, recitation of fixed texts, performance of special music, songs or dances, processions, manipulation of certain objects, use of special dresses, consumption of special food, drink, or drugs, and much more. Religious rituals have also included animal sacrifice, human sacrifice, ritual suicide, and ritual murder. Ritual lamentation -- song performed with weeping -- in many societies was regarded as required to ritually carry the departed soul to a safe afterlife (Tolbert 1990a, 1990b; Wilce 2006).

Purposes

Ritual serves diverse purposes including, but not limited to:

• Worship
• Ritual purification with the aim of removing uncleanliness, which may be real or symbolic.
• Atonement
• Dedication
• Education

Religious

main: Worship In religion, a ritual can comprise the prescribed outward forms of performing the cultus, or cult, of a particular observation within a religion or religious denomination. Although ritual is often used in context with worship performed in a church, the actual relationship between any religion's doctrine and its ritual(s) can vary considerably from organized religion to non-institutionalized spirituality, such as ayahuasca shamanism as practiced by the Urarina of the upper Amazon. Rituals often have a close connection with reverence, thus a ritual in many cases expresses reverence for a deity or idealized state of humanity.
