Yoginīs, called jognīs in the Upper Kulu Valley region, are supernatural beings, from ancient cults. They are numerous and they live in an egalitarian group, without structure or hierarchy.
The term chidrā, used for the purification ritual in Kayika, finds its possible origin in the OIA chidra, meaning ‘hole’ or ‛weak point’ as a noun and ‘perforated’ or ‘torn asunder’ as an adjective. The exact meaning of chidrā, however, varies depending on the context in which it is employed: ‘release’ from transgression (pāp), ritual or social, ‘removal’ of evil power of deity (dosh-khot), ‘cutting’ of spells and bad omens (kari-shrapni), and so on.
The origin behind the worship of these village deities is lost in time. Oral religious traditions (such as bhārthā or ganāi, lit. news) and folklore connected with them gives a rough idea of how things may have been, but proper research is lacking in this regard. Many of the deities are nowadays associated with gods and goddesses of the Hindu pantheon. It is obvious that Hinduism must have arrived in Kulu in the distant past and Buddhism flourished here as well. However, the religion at present of the Kulu people living in its villages, termed as Hinduism, in actuality is an amalgamation of different religious ideas and customs having the aboriginal nature worship at its core.
