“Enq: But what is it that reincarnates, in your belief?
Theo: The Spiritual thinking Ego, the permanent principle in man, or that which is the seat of Manas.
It is not Atma, or even Atma-Buddhi, regarded as the dual Monad, which is the individual, or divine man, but Manas; for Atman is the Universal ALL, and becomes the HIGHER-SELF of man only in conjunction with Buddhi, its vehicle, which links IT to the individuality (or divine man).
For it is the Buddhi-Manas which is called the Casual body, (the United 5th and 6th Principles) and which is Consciousness, that connects it with every personality it inhabits on earth.
Therefore, Soul being a generic term, there are in men three aspects of Soul – the terrestrial, or animal; the Human Soul; and the Spiritual Soul; these, strictly speaking, are one Soul in its three aspects.
Now of the first aspect, nothing remains after death; of the second (nous or Manas) only its divine essence if left unsoiled survives, while the third in addition to being immortal becomes consciously divine, by the assimilation of the higher Manas. But to make it clear, we have to say a few words first of all about Reincarnation.
Enq: You will do well, as it is against this doctrine that your enemies fight the most ferociously.
Theo: You mean the Spiritualists? I know; and many are the absurd objections laboriously spun by them over the pages of Light. So obtuse and malicious are some of them, that they will stop at nothing.
One of them found recently a contradiction, which he gravely discusses in a letter to that journal, in two statements picked out of Mr. Sinnett’s lectures. He discovers that grave contradiction in these two sentences: “Premature returns to earth-life in the cases when they occur may be due to Karmic complication…”; and “there is no accident in the supreme act of divine justice guiding evolution.”
So profound a thinker would surely see a contradiction of the law of gravitation if a man stretched out his hand to stop a falling stone from crushing the head of a child!”
