“Q: But the two, the higher and the lower, Manas are one, are they not?
A: They are, and yet they are not – and that is the great mystery. The Higher Manas or EGO is essentially divine, and therefore pure; no stain can pollute it, as no punishment can reach it, per se, the more so since it is innocent of, and takes no part in, the deliberate transactions of its Lower Ego.
Yet by the very fact that, though dual and during life the Higher is distinct from the Lower, “the Father and Son” are one, and because that in reuniting with the parent Ego, the Lower Soul fastens upon and impresses upon it all its bad as well as good actions – both have to suffer, the Higher Ego, though innocent and without blemish, has to bear the punishment of the misdeeds committed by the lower Self together with it in their future incarnation.
The whole doctrine of atonement is built upon this old esoteric tenet; for the Higher Ego is the antitype of that which is on this earth the type, namely the personality. It is, for those who understand it, the old Vedic story of Visvakarman over again, practically demonstrated.
Visvakarman, the all-seeing Father-God, who is beyond the comprehension of mortals, ends, as son of Bhuvana, the holy Spirit, by sacrificing himself to himself, to save the worlds.
The mystic name of the “Higher Ego” is, in the Indian philosophy, Kshetrajna, or “embodied Spirit”, that which knows or informs kshetra, “the body”. Etymologize the name, and you will find in it the term aja, “first-born”, and also the “lamb”.
All this is very suggestive, and volumes might be written upon the pregenetic and postgenetic development of type and antitype – of Christ-Kshetrajna, the “God-Man”, the First-born, symbolized as the “lamb”.
The Secret Doctrine shows that the Manasa-Putras or incarnating EGOS have taken upon themselves, voluntarily and knowingly, the burden of all the future sins of their future personalities. Thence it is easy to see that it is neither Mr. A. nor Mr. B., nor any of the personalities that periodically clothe the Self-Sacrificing EGO, which are the real Sufferers, but verily the innocent Christos within us.
Hence the mystic Hindus say that the Eternal Self, or the Ego (the one in three and three in one), is the “Charioteer” or driver; the personalities are the temporary and evanescent passengers; while the horses are the animal passions of man.
It is, then, true to say that when we remain deaf to the Voice of our Conscience, we crucify the Christos within us.
But let us return to dreams.”
