“Enq: But are there no modes of communication between the Spiritual and human consciousness or memory?
Theo: Of course there are; but they have never been recognized by your scientific modern psychologists. To what do you attribute intuition, the “voice of the conscience”, premonitions, vague undefined reminiscences, etc., etc., if not to such communications?
Would that the majority of educated men, at least, had the fine spiritual perceptions of Coleridge, who show how intuitional he is in some of his comments. Hear what he says with respect to the probability that “all thoughts are in themselves imperishable.”
“If the intelligent faculty (sudden ‘revivals’ of memory) should be rendered more comprehensive, it would require only a different and appropriate organization, the body celestial instead of the body terrestrial, to bring before every human soul the collective experience of its whole past existence (existences, rather).”
And this body celestial is our Manasic EGO.”
