"If we bear in mind the definition of the chief Egyptian gods by Plutarch, these myths will become more comprehensible; as he well says: 'Osiris represents the beginning and principle; Isis, that which receives; and Horus, the compound of both. Horus engendered between them, is not eternal nor incorruptible, but, being always in generation, he endeavours by vicissitudes of imitations, and by periodical passion [suffering] (yearly re-awakening to life) to continue always young, as if he should never die.' Thus, since Horus is the personified physical world, Aroueris, or the 'elder Horus' is the ideal Universe; and this accounts for the saying that 'he was begotten by Osiris and Isis when these were still in the bosom of their mother' -- Space" (TG 31).
And further: "the older Horus was the Idea of the world remaining in the demiurgic mind 'born in Darkness before the creation of the world'; the second Horus was the same Idea going forth from the Logos, becoming clothed with matter and assuming an actual existence" (SD 1:366).
