Stanza VII
1. Behold the beginings of sentient formless life. First the Divine, the one from the Mother-Spirit; then the Spiritual; the three from the one, the four from the one, and the five from which the three, the five, and the seven. These are the three-fold, the four-fold downward; the “mind-born” sons of the first Lord; the shining seven. It is they who are thou, me, him, oh Lanoo. They, who watch over thee, and thy mother earth.
2. The one ray multiplies the smaller rays. Life precedes form, and lfe survives the last atom of form. Through the countless rays proceeds the life-ray, the one, like a thread through many jewels.
3. When the one becomes two, the threefold appears, and the three are one; and it is our thread, oh Lanoo, the heart of the man-plant called Saptaparna.
Mme. Blavatsky (cont): “Now, you understand the idea. One calls it the Unknowable, and the other the Unknown. It is positively a contradiction in terms, and both mean quite a different thing; and yet, the same thing.
Because Herbert Spencer calls that which we would call the First Logos – or the first manifestation, the radiation from the eternal – he calls it the first cause; and then he speaks about the Unknowable. The other one speaks of the Unknown and wants to make of the Unknown the Parabrahm. You understand? But the Parabrahm {is} entirely unconsciousness, that is to say, a negative quantity, as he calls it.
Now, what we Occultists say is that neither Spencer nor Harrison offers anything like a complete philosophy. The Unknowable or the Unknown could not exist for our perceptions, nor could our perceptions for it.
It is the Unknown, or the Invisible manifesting the Logos, which we place face to face with every phenomenon – abstract, physical, psychic, mental, or spiritual – because the Unknown will always contain in itself some portion of the Unknowable, that is to say, some of the laws and manifestations which elude our perception for a time.
On the other hand, Unknowable, being the sum of all that which owing to our finite intellectual organization may elude forever our perceptions, is the Parabrahm, or the causeless cause.
Now, if I have succeeded in making myself understood, then I say if you study Spencer’s Unknowable, and take Harrison’s Unknown, instead of accepting either one or the other, seeing the necessary complements of each one life, then our one abstract Monad, and our one universal Prana, whose eternal, immutable, causeless cause is our Vedantic Parabrahm at one end of the line, and the great being, the human race or humanity at the other, then you will have the true idea of what the Occultists mean.
You see it is this humanity and each unit in it which are, at one and the same time, the Unknowable, the Unknown, and the To-Be-Known.
This is what Occultism says: as it is impossible for the human mind to know anything definite even of the unknown essence, so let us turn our whole attention to its highest manifestation on earth, mankind, and say as is said in John: “In it we live and move and have our being” – “Illon vivicuus movemur et sumus” (Acts 17:28, “For in him we live, and move, and have our being – In ipso enim vivimus et movemur et sumus.” – Paul quotes Epimenides of Knossos – Crete).”
