Not only does it thus direct itself to the intelligence and the emotions, but it seeks, as said, to stimulate the unfoldment of the spiritual nature. It answers to that inner impulse which exists in humanity, and which is ever pushing the race onwards. For deeply within the heart of all--often overlaid by transitory conditions, often submerged under pressing interests and anxieties--there exists a continual seeking after God. "As the hart panteth after the water-brooks, so panteth"[7] humanity after God. The search is sometimes checked for a space, and the yearning seems to disappear. Phases recur in civilisation and in thought, wherein this cry of the human Spirit for the divine--seeking its source as water seeks its level, to borrow a simile from Giordano Bruno--this yearning of the human Spirit for that which is akin to it in the universe, of the part for the whole, seems to be stilled, to have vanished; none the less does that yearning reappear, and once more the same cry rings out from the Spirit. Trampled on for a time, apparently destroyed, though the tendency may be, it rises again and again with inextinguishable persistence, it repeats itself again and again, no matter how often it is silenced; and it thus proves itself to be an inherent tendency in human nature, an ineradicable constituent thereof. Those who declare triumphantly, "Lo! it is dead!" find it facing them again with undiminished vitality. Those who build without allowing for it find their well-constructed edifices riven as by an earthquake. Those who hold it to be outgrown find the wildest superstitions succeed its denial. So much is it an integral part of humanity, that man _will_ have some answer to his questionings; rather an answer that is false, than none. If he cannot find religious truth, he will take religious error rather than no religion, and will accept the crudest and most incongruous ideals rather than admit that the ideal is non-existent. Religion, then, meets this craving, and taking hold of the constituent in human nature that gives rise to it, trains it, strengthens it, purifies it and guides it towards its proper ending--the union of the human Spirit with the divine, so "that God may be all in all."[8]
