Just as the characteristic attributes of the mana are found in the soul, so secondary and superficial changes are enough to enable the mana to individualize itself in the form of a soul. We pass from the first idea to the second with no break of continuity. Every religious force which is attached in a special way to a determined being participates in the characteristics of this being, takes on its appearance and becomes its spiritual double. Tregear, in his Maori-Polynesian dictionary, has thought it possible to connect the word _mana_ with another group of words, such as _manawa_, _manamana_, etc., which seem to belong to the same family, and which signify heart, life, consciousness.[862] Is this not equivalent to saying that some sort of kinship ought to exist between the corresponding ideas as well, that is to say, between the idea of impersonal force and those of internal life, mental force and, in a word, of the soul? This is why the question whether the churinga is sacred because it serves as the residence of a soul, as Spencer and Gillen believe, or because it has impersonal virtues, as Strehlow thinks, seems to us to have little interest and to be without sociological importance. Whether the efficacy of a sacred object is represented in an abstract form in the mind or is attributed to some personal agent does not really matter. The psychological roots of both beliefs are identical: an object is sacred because it inspires, in one way or another, a collective sentiment of respect which removes it from profane touches. In order to explain this sentiment, men sometimes fall back on to a vague and imprecise cause, and sometimes on to a determined spiritual being endowed with a name and a history; but these different interpretations are superadded to one fundamental phenomenon which is the same in both cases.
