VII- Dreams and After Death States: The Invisible Worlds

3) Navigating Through Time - The Rights Of Passage

(HPB, Secret Doctrine, Vol I, p. 16)
The following summary will afford a clearer idea to the reader.
    (1.) The ABSOLUTE; the Parabrahm of the Vedantins or the one Reality, SAT, which is, as Hegel says, both Absolute Being and Non-Being.
    (2.) The first manifestation, the impersonal, and, in philosophy, unmanifested Logos, the precursor of the "manifested." This is the "First Cause," the "Unconscious" of European Pantheists.
    (3.) Spirit-matter, LIFE; the "Spirit of the Universe," the Purusha and Prakriti, or the second Logos.
    (4.) Cosmic Ideation, MAHAT or Intelligence, the Universal World-Soul, the Cosmic Noumenon of Matter, the basis of the intelligent operations in and of Nature, also called MAHA-BUDDHI.
The One REALITY; its dual aspects in the conditioned Universe.
Further, the Secret Doctrine affirms:-
           (b.) The Eternity of the Universe in toto as a boundless plane; periodically "the playground of numberless Universes incessantly manifesting and disappearing," called "the manifesting stars," and the "sparks of Eternity." "The Eternity of the Pilgrim"† is like a wink
-----
† "Pilgrim" is the appellation given to our Monad (the two in one) during its cycle of incarnations. It is the only immortal and eternal principle in us, being an indivisible part of the integral whole-the Universal spirit, from which it emanates, and into which it is absorbed at the end of the cycle. When it is said to emanate from the one

Moreover, the Secret Doctrine teaches: --
(c) The fundamental identity of all Souls with the Universal Over-Soul, the latter being itself an aspect of the Unknown Root; and the obligatory pilgrimage for every Soul -- a spark of the former -- through the Cycle of Incarnation(or"Necessity") in accordance with Cyclic and Karmic law, during the whole term. In other words, no purely spiritual Buddhi (divine Soul) can have an independent (conscious) existence before the spark which issued from the pure Essence of the Universal Sixth principle, -- or the OVER-SOUL, -- has (a) passed through every elemental form of the phenomenal world of that Manvantara, and (b) acquired individuality, first by natural impulse, and then by self-induced and self-devised efforts (checked by its Karma), thus ascending through all the degrees of intelligence, from the lowest to the highest Manas, from mineral and plant, up to the holiest archangel (Dhyani-Buddha). The pivotal doctrine of the Esoteric philosophy admits no privileges or special gifts in man, save those won by his own Ego through personal effort and merit throughout a long series of metempsychoses and reincarnations.

(HPB, Secret Doctrine, Vol I, p. 37)
(a) Time is only an illusion produced by the succession of our states of consciousness as we travel through eternal duration, and it does not exist where no consciousness exists in which the illusion can be produced; but "lies asleep." The present is only a mathematical line which divides that part of eternal duration which we call the future, from that part which we call the past. Nothing on earth has real duration, for nothing remains without change-or the same-for the billionth part of a second; and the sensation we have of the actuality of the division of "time" known as the present, comes from the blurring of that momentary glimpse, or succession of glimpses, of things that our senses give us, as those things pass from the region of ideals which we call the future, to the region of memories that we name the past. ….The real person or thing does not consist solely of what is seen at any particular moment, but is composed of the sum of all its various and changing conditions from its appearance in the material form to its disappearance from the earth. It is these "sum-totals" that exist from eternity in the "future," and pass by degrees through matter, to exist for eternity in the "past." …..Even so of persons and things, which, dropping out of the to-be into the has-been, out of the future into the past - present momentarily to our senses a cross-section, as it were, of their total selves, as they pass through time and space (as matter) on their way from one eternity to another: and these two constitute that "duration" in which alone anything has true existence, were our senses but able to cognize it there.

(Wm. Q. Judge, Articles, I: pp. 536-537)
Man is a Soul, and as such stands among material things. This Soul is not only on its way upward for itself, but is compelled at the same time to draw up, refine, purge and perfect gross matter-so called- in which it is compelled to live. ……….. These sheaths are necessary if the Soul is to know or act. For it cannot by itself understand Nature at all, but transforms instantly all sensations and ideas by means of the different sheaths, until in the process it has directed body below it; and in like manner they report from below upward in the case of sensations from natural phenomena and impressions on the outside
