“Mr. Old: There is no individual consciousness. How do we know anything about Nirvana?
Mr. Kingsland: Do you believe that the future Manvantara will be an improvement upon the present one, or not?
Mr. Old: Yes! I do, because my experience has told me from what little I have seen that the law of nature is progression.
Mr. Kingsland: Is not that the same as saying it is experience?
Mr. Old: Plus analogy.
Mr. Kingsland: I am drawing the analogy now. I say you can carry it not only from your past life to the present, but from the past Manvantara to the next Manvantara.
Mr. B. Keightley: If you ever read Froude (James Anthony Froude, English writer), he talks about the faculty of apprehending abstract ideas. HPB, answer this, if you can, from the point of view of exotericism. Is the apprehension of highest abstract ideas the function of Manas, or of Buddhi?
Mme. Blavatsky: Buddhi can have the apprehension of nothing.
Mr. B. Keightley: There you are answered, Old.
Mr. Old: Yes! Certainly.
Mme. Blavatsky: If we argue or discuss about the universe we had better leave the first two thing – Parabrahm, and the first Logos, call it; and when we speak of men, let us remember that it is a perfect analogy – that that which we call Parabrahm in the first Logos is in man, Atma, and Buddhi. Then as we begin by the third or second Logos, so we must begin by Manas, because there it is where the point of differentiation begins, otherwise you are lost. You will only make confusion, otherwise.
Mr. Old: It is having to keep parallel texts before you all the time. Knowing certain teachings on the one side of the book, and trying to keep them parallel.
Mme. Blavatsky: He will come and reproach us that he knows too much.
Mr. Old: I refer to esoteric teaching.
Mme. Blavatsky: Most assuredly; therefore, every time you put this question, I say, do go to bed, let us talk of something else; let us talk about exoteric subjects, of which we can discuss as much as you like, but the others – well, it is very difficult to speak of that which we had better keep silent about.”
