Sila is one of the more abstract and philosophically significant figures in Inuit cosmology, generally described not as a personal god with a human-like form and biography, in the way Sedna is, but as a great, pervasive force encompassing weather, the air, and the animating breath of life itself, closer in character to a cosmic principle than to an individual deity a person might picture or address by direct petition.
Early twentieth-century ethnographic recording, including the influential work of explorer and ethnographer Knud Rasmussen among Inuit communities, described Sila as capable of both benevolent calm and violent, destructive storm, an ambivalence read as reflecting the genuinely unpredictable and life-threatening character of Arctic weather itself, which traditional Inuit life had to work with and around rather than simply endure passively. Some accounts describe Sila as connected to or expressed through the wind and open air specifically, a force that could be sensed and responded to by an experienced hunter or angakkuq attentive to its signs, rather than a distant deity relevant only in formal ritual.
