The fullest documented account of a vision quest practice comes from the Lakota rite of hanbleceya, crying for a vision, recorded in Joseph Epes Brown's The Sacred Pipe: Black Elk's Account of the Seven Rites of the Oglala Sioux (1953), based on interviews with the Oglala holy man Black Elk. A seeker, typically guided in preparation by an elder or medicine person, goes alone to an isolated hilltop or chosen site and fasts without food or water for one to four days, praying with the sacred pipe and awaiting a vision, which may arrive as an animal, a voice, or another symbolic experience. On return, the vision is related to and interpreted by an elder qualified to do so, and may set the course of the seeker's later religious role.
This is one specifically documented nation's practice under its own Lakota name and protocol. Other Native nations that hold comparable fasting and vision traditions have their own distinct terms, timing and requirements, not detailed here, and this entry should not be read as describing a single pan-Indian rite.
The length and severity of the fast, the specific site chosen, and the presence or absence of a guiding elder during the isolation itself vary by community and by the individual seeker's circumstances; Brown's account notes that preparation for the rite, including instruction from an elder and ritual purification beforehand, is treated as integral to a properly conducted hanbleceya rather than an optional preliminary.
