In the vegetable world, too, there is the power of growth, and that power of growth is the spirit. In the animal world there is the sense of feeling, but in the human world there is an all-embracing power. In all the preceding stages the power of reason is absent, but the soul existeth and revealeth itself. The sense of feeling understandeth not the soul, whereas the reasoning power of the mind proveth the existence thereof. In like manner the mind proveth the existence of an unseen Reality that embraceth all beings, and that existeth and revealeth itself in all stages, the essence whereof is beyond the grasp of the mind. Thus the mineral world understandeth neither the nature nor the perfections of the vegetable world; the vegetable world understandeth not the nature of the animal world, neither the animal world the nature of the reality of man that discovereth and embraceth all things. The animal is the captive of nature and cannot transgress the rules and laws thereof. In man, however, there is a discovering power that transcendeth the world of nature and controlleth and interfereth with the laws thereof. For instance, all minerals, plants and animals are captives of nature. The sun itself with all its majesty is so subservient to nature that it hath no will of its own and cannot deviate a hair's-breadth from the laws thereof. In like manner all other beings, whether of the mineral, the vegetable or the animal world, cannot deviate from the laws of nature, nay, all are the slaves thereof. Man, however, though in body the captive of nature is yet free in his mind and soul, and hath the mastery over nature. Consider: according to the law of nature man liveth, moveth and hath his being on earth, yet his soul and mind interfere with the laws thereof, and [Pages 11-20] even as the bird he flieth in the air, saileth speedily upon the seas and as the fish soundeth the deep and discovereth the things therein. Verily this is a grievous defeat inflicted upon the laws of nature.
