Please help ... What is meant by 'Arming' here in this context? Thanks?
. At the solemn hour of sunrise or sunset took up his position, overlooking the glories of earth and facing the "Great Mystery," and there he remained, naked, erect, silent, and motionless, exposed to the elements and forces of His arming, for a night and a day to two days and nights, but rarely longer. Sometimes he would chant a hymn without words, or offer the ceremonial "filled pipe ." In this holy trance or ecstasy the Indian mystic found his highest happiness and the motive power of his existence.
