We have now paved the way for understanding what is meant by "the unity of the spirit." In the first conception of spirit as the underlying origin of all things we see a universal substance which, at this stage, is not differentiated into any specific forms. This is not a question of some bygone time, but subsists at every moment of all time in the _innermost_ nature of all being; and when we see this, we see that the division between one specific form and another has below it a deep essential unity, which acts as the supporter of all the several forms of individuality arising out of it. And as our thought penetrates deeper into the nature of this all-producing spiritual substance we see that it cannot be limited to any one portion of space, but must be limitless as space itself, and that the idea of any portion of space where it is not is inconceivable. It is one of those intuitive perceptions from which the human mind can never get away that this primordial, all-generating living spirit must be commensurate with infinitude, and we can therefore never think of it otherwise than as universal or infinite. Now it is a mathematical truth that the infinite must be a unity. You cannot have two infinites, for then neither would be infinite, each would be limited by the other, nor can you split the infinite up into fractions. The infinite is mathematically essential unity. This is a point on which too much stress cannot be laid, for there follow from it the most important consequences. Unity, as such, can be neither multiplied nor divided, for either operation destroys the unity. By multiplying, we produce a plurality of units of the same scale as the original; and by dividing, we produce a plurality of units of a smaller scale; and a plurality of units is not unity but multiplicity. Therefore if we would penetrate below the outward nature of the individual to that innermost principle of his being from which his individuality takes its rise, we can do so only by passing beyond the conception of individual existence into that of the unity of universal being. This may appear to be a merely philosophical abstraction, but the student who would produce practical results must realize that these abstract generalizations are the foundation of the practical work he is going to do.
