Aytal’s reference is the Shamanism Shamanism is a religious practice that involves a practitioner (shaman) interacting with what they believe to be a spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination or to in some other way aid human beings. The Modern English word shamanism derives from the Russian word šamán, which itself comes from the word samān from a Tungusic language – possibly from the southwestern dialect of the Evenki spoken by the Sym Evenki peoples, or from the Manchu language. The etymology of the word is sometimes connected to the Tungus root sā-, meaning "to know". However, Juha Janhunen questions this connection on linguistic grounds: "The possibility cannot be completely rejected, but neither should it be accepted without reservation since the assumed derivational relationship is phonologically irregular (note especially the vowel quantities)." According to archaeology, shamanic rituals were practiced in Siberia in the Neolithic era and in the Bronze Age. Unlike most of the religious teachings created by one or another founder, shamanism has developed in a natural, historical way. At a certain stage of the reflection of the world in the minds of people, the image of the mythical Universe became so significant and developed that only individuals who had special abilities and had special training could understand it. In most societies, there is a need for an "intermediary" between the human and otherworldly worlds. One of the most ancient shamanic burials in Russia was found on Deer Island in Lake Onega and probably dates back to the Mesolithic era, dating back 6 thousand years.
