means The idea that the divine, or some animating principle, exists within and throughout the material world rather than standing apart from it.

from From Latin 'immanere,' to remain or dwell within — built from 'in-' (in) plus 'manere' (to stay, the same root behind 'mansion' and 'permanent'). The word entered philosophical and theological English to mark a careful contrast with 'transcendence' (from 'transcendere,' to climb beyond): one God stays home, the other steps outside. Worth not confusing with 'imminence,' from 'imminere' (to overhang, to loom) — that one is about what's about to happen, not what's already inside.
