Excerpts from The Key to Theosophy, by H.P. Blavatsky
Q: Having told me what God, the Soul and Man are not, in your views, can you inform me what they are, according to your teachings?
A: In their origin and in eternity the three, like the universe and all therein, are one with the absolute Unity, the unknowable deific essence I spoke about some time back. We believe in no creation, but in the periodical and consecutive appearances of the universe from the subjective onto the objective plane of being, at regular intervals of time, covering periods of immense duration.
Q: Can you elaborate the subject?
A: Take as a first comparison and a help towards a more correct conception, the solar year, and as a second, the two halves of that year, producing each a day and a night of six months’ duration at the North Pole. Now imagine, if you can, instead of a Solar year of 365 days, eternity. Let the sun represent the universe, and the polar days and nights of six months each — days and nights lasting each 182 trillions and quadrillions of years, instead of 182 days each. As the sun arises every morning on our objective horizon out of its (to us) subjective and antipodal space, so does the Universe emerge periodically on the plane of objectivity, issuing from that of subjectivity — the antipodes of the former. This is the “Cycle of Life”. And as the sun disappears from our horizon, so does the Universe disappear at regular periods, when the “Universal night” sets in. The Hindus call such alternations the “Days and Nights of Brahm” , or the time of Manvantara and that of Pralaya (dissolution). The Westerns may call them Universal Days and Nights if they prefer. During the latter (the nights) All is in All; every atom is resolved into one Homogeneity.
