Theosophers engage in analysis of the universe, humanity, divinity, and the reciprocal effects of each on the other. The starting point for theosophers may be knowledge of external things in the world or inner experiences and the aim of the theosopher is to discover deeper meanings in the natural or divine realm. Antoine Faivre notes, "the theosophist dedicates his energy to inventing (in the word's original sense of 'discovering') the articulation of all things visible and invisible, by examining both divinity and nature in the smallest detail." The knowledge that is acquired through meditation is believed to change the being of the meditator.
