In Inuit mythology, Silap Inua ('possessor of spirit') or Silla ('breath, spirit') was, similar to mana or ether, the primary component of everything that exists; it is also the breath of life and the method of locomotion for any movement or change. Silla is believed to control everything that goes on in one's life.
Silla is a deity of the sky, the wind, and of weather. Though identified as male, he is never depicted, and thought to be formless. There are very few myths in which Silla is a character, because he is not thought to have many personality characteristics. He also represents a concept somewhat akin to the Hindu idea of Paramatman, or Emerson’s idea of the great Over soul: Silla is also the substance of which souls are made of. Contrary to the Christian missionaries who have identified Nanook the polar bear spirit as the supreme deity of the Inuit, Silla is much closer to this role. However, Silla also has a somewhat malevolent aspect: he is known to lure children away from their play off into the tundra, never to be seen again.
Among the many various Eskimo cultures, term silap inua / sila, hillap inua / hilla (among Inuit), siḷam iñua (among Inupiaq), ellam yua / ella (among Yup'ik) is used with some diversity. In many instances it refers “outer space”, “intellect”, “weather”, “sky”, “universe”: there may be some correspondence with the presocratic concept of logos.
Shamanhood among Eskimo peoples was a diverse phenomenon, just like the various Eskimo cultures themselves. Among Copper Inuit, shamans were believed to obtain their power from this “Wind Indweller”, thus even their helping spirits were termed as silap inue.
Among Siberian Yupik, was depicted as a mighty hunter, catching game just like earthly men, but being capable of controlling whether people paid attention to customs and traditions.
In Sireniki Eskimo language, the word has meanings “universe”, “outer world”, “space”, “free space”, “weather”.
