“Elemental deva lives form the substance of unevolved and intelligent human desires and thoughts. As the human attributes become more refined, so also the quality of the deva lives that incarnate to embody those attributes. When one progresses upon the path and the more base elemental lives are to be expelled, then a period of sickness often occurs at the places of exit of that substance.”
