Neither need concern us at present, except to note the reference to herbs in this same context. Continuing with the Enigma of the Sages , we have already met the triadic set: "body," "soul," and "spirit" in Section VI in both alchemical and strictly quantified astronomical contexts, - Distance, Period and Velocity respectively - and true enough, if any one parameter is known the remaining pair are readily obtainable.
