There are seven kingdoms. The first group comprises three degrees of elementals, or nascent centres of forces—from the first stage of differentiation of [from] Mûlaprakriti [or rather Pradhâna, Primordial Homogeneous Matter] to its third degree—_i.e._, from full unconsciousness to semi‐perception; the second or higher group embraces the kingdoms from vegetable to man; the mineral kingdom thus forming the central or turning point in the degrees of the “Monadic Essence,” considered as an evolving energy. Three stages [sub‐physical] on the elemental side; the mineral kingdom; three stages on the objective physical(288) side—these are the [first or preliminary] seven links of the evolutionary chain.(289) “Preliminary” because they are preparatory, and though belonging in fact to the natural, they would be more correctly described as the sub‐natural evolution. This process makes a halt in its stages at the third, at the threshold of the fourth stage, when it becomes, on the plane of natural evolution, the first really manward stage, thus forming with the three elemental kingdoms, the ten, the Sephirothal number. It is at this point that begins: A descent of spirit into matter equivalent to an ascent in physical evolution; a reäscent from the deepest depths of materiality (the mineral) towards its _status quo ante_, with a corresponding dissipation of concrete organism—up to Nirvâna, the vanishing point of differentiated matter.(290) Therefore it becomes evident, why that which is pertinently called in _Esoteric Buddhism_ “wave of evolution,” and “mineral, vegetable, animal and man‐impulse,” stops at the door of our Globe, at its Fourth Cycle or Round. It is at this point that the Cosmic Monad (Buddhi) will be wedded to, and become the vehicle of, the Âtmic Ray; _i.e._, Buddhi will awaken to an apperception of it (Âtman), and thus enter on the first step of a new septenary ladder of evolution, which will lead it eventually to the tenth, counting from the lowest upwards, of the Sephirothal Tree, the Crown. Everything in the Universe follows analogy. “As above, so below”; Man is the microcosm of the Universe. That which takes place on the spiritual plane, repeats itself on the cosmic plane. Concretion follows the lines of abstraction; corresponding to the highest must be the lowest; the material to the spiritual. Thus, corresponding to the Sephirothal Crown, or Upper Triad, there are the three elemental kingdoms, which precede the mineral,(291) and which, using the language of the Kabalists, answer in the cosmic differentiation to the Worlds of Form and Matter, from the Super‐Spiritual to the Archetypal. Now what is a Monad? And what relation does it bear to an Atom? The following reply is based upon the explanations given in answer to these questions in the above‐cited article, “The Mineral Monad,” written by the author. To the second question it is answered:
