For instance, as the basis of every "cycle of life" is found the egg or germ, that strange microcosm which appears to contain within itself the entire organism from which it proceeds and which seems capable of manifesting it in its entirety. The first embryologic discovery we make as the result of this study--a discovery of the utmost importance--is that germs are one in essence, and are all endowed with the same possibilities and potentialities. The only difference that can be found in them is that the more evolved have acquired the power of developing, in the same cycle, a greater number of links, so to speak, in the chain of forms that proceeds from the atom to the sheath, or envelope, of the Gods-Men. Thus, the highest germ which the microscope enables us to follow--the human ovule--is first a kind of mineral represented by the nucleus (the point, unity) of its germinal cell; then it takes the vegetable form--a radicle, crowned by two cotyledons (duality); afterwards it becomes a fish (multiplicity), which is successively transformed into a batrachian, then a bird, afterwards assuming more and more complex animal forms, until, about the third month of foetal life, it appears in the human form. The process of transformation is more rapid when Nature has repeated it a certain number of times; it then represents a more extensive portion of the ladder of evolution, but, be it noted, the process is the same for all, and for all the ladder is composed of the same number of steps; beings start from the same point, follow the same path and halt at the same stages; nothing but their age causes their inequalities. They are more than brothers, they are all representatives of the One, that which is at the root of the Universe, Divinity, supreme Being.
