A note: the arrows show the process dynamics in the Absolute.
The main thing to be taken into account when studying this scheme is that it reflects multidimensionality (multilokaness) of space. Therefore, that which is shown at the bottom of the scheme corresponds to that, which is located in the deep, in the subtlest lokas. And that, which is shown higher on the chime, corresponds to lokas of increasing density (or coarseness). In other words, the downward direction on the scheme denotes the inward direction inside the multidimensional Body of the Absolute, while the upward one — is the direction towards Its outer layers.
One must not view the sectors shown on the scheme as really existing in the Universe. In reality, these are not sectors, but rather layers of multidimensionality.
Note, that the multidimensionality cannot be explored with physical devices, since they cannot be brought from the physical world into the other lokas. The only thing, with which a spiritual seeker can perceive reality of other lokas, is his refined consciousness, developed by means of buddhi-yoga (a system for consciousness development). Such a developed consciousness is capable of moving freely from one loka to another.
In the language of material science, one can say that everything that takes place in the non-physical lokas is of “lepton” nature. But it is clear, that this statement per se does not provide sufficient information for solving the problems under consideration.
Let us begin our analysis of the diagram by looking at the bottom of the scheme, which represents the deepest level of multidimensional space.
In the universal Void there abides the most subtle energy state of the deepest layer of the Absolute — Ishvara (God-the-Father, the Creator, Jehovah, Allah, Tao, Adibuddha: these and other words are used in different languages to name Him). On the scheme, His Abode is shown to the right had side above the Void.
Now let us look at the unbroken vertical line. This line represents the "Mirror", the actually existing membrane that separates the entire Absolute. To the right from this line (on the scheme), there are three basic eternal components of the Absolute: Ishvara in His Abode (the "Bridal Chamber", as apostle Philip, a disciple of Jesus Christ, called It ), and more dense akasha "floors" — lokas of protopurusha and protoprakriti.
To the left from the "Mirror" there are derivatives of the Absolute's basic states: lokas of Brahman (the Higher Purusha), the Primordial Purusha, and prakriti. They exist only during Kalpas in “manifested worlds” of the universe — "islets" of the Creation, which appear at the beginning and disappear at the end of each Kalpa, being consumed by akasha. When "the end of the world" (Pralaya) comes for such an “islet”, its matter turns back into protoprakriti, and individual souls, who did not want to or did not succeed in attaining Perfection (i.e. to attaining Divinity and merging with consciousness of the Higher or the Highest Purusha) by that time after numerous incarnations, disintegrate down to the state of protopurusha.
Note, that during Kalpas (i.e. during existence of material “islets” of the Creation), the amount of prakriti (because of photosynthesis, in particular) and purusha (because of the increase of the amount of energy of consciousness of individual souls, who feed on prakriti) increases and at the end of Kalpa replenishes the cosmic stores of protoprakriti and protopurusha. Therefore, the amount of the latter does not change significantly.
All that is shown on the scheme above the first level of the Absolute represents the "sphere of activity" of Brahman, the "Brahman's world" (in Sanskrit — "aparabrahman", i.e. that, which is not Divine Brahman).
Now let us look at the leftmost column on the scheme. It illustrates states of souls during Kalpa. Souls of different levels of subtlety-coarseness (in terms of emotional states, in which they used to live during incarnations) are distributed over the layers of multidimensional space, as it were on the background of the main lokas. The layer of more subtle energy (the “first floor” on the scheme) is called a "paradise", while the coarsest one (the topmost one on the scheme) — is called "hell". The layer between them contains souls in the intermediate state of being attached to material plane. The most commonly used name for this layer is the "astral plane". (For more details see [5,7]).
Now let us look at the process of soul evolution in more details from the beginning.
When conditions on some planet are suitable for existence of organic life on it (as it is currently the case on Earth), there starts the process of development of particles of purusha, that form of protopurusha. This process begins on crystalline lattices of minerals and then continues in organic bodies, which also evolve along with souls. Metabolic processes that go on in organic bodies allow the transformation of prakriti into energy of purusha (i.e. individual souls that grow during the embodied state). This ensures the quantitative growth of souls.
Embodied souls of highly developed animal species and human beings have significant amount of free will, so they evolve being subject to the “law of karma”. In parallel, the majority of them develop intellectual abilities and some people get a chance to begin a conscious spiritual self-perfection. But some of them remain "materialists" — they are unaware of anything but matter and consider themselves as material bodies. Their way of life is not different essentially from that of many animals.
Those souls, who habituate themselves to living in coarse emotional states, go to hellish lokas, shown in the top left part of the scheme. It is the "outer darkness", in the New Testament’s language. The destiny of such souls is to be embodied again in "hellish" conditions on Earth or to be disintegrated to the state of protopurusha even before the Kalpa ends.
So, all people can be divided into three categories: the intermediate group of "materialists", demoniac people, and people who seek spiritual Perfection, i.e. Union with God.
For the latter group, the main component of spiritual self-realization should consist in development of the spiritual heart — the energy of the anahata chakra (see [7,9]). An optimal achievement for them is Mergence (as consciousness, or buddhi) with the Higher Purusha or even Entering the Abode of the Creator and Mergence with Him there. One must learn to live in these states during one’s life in the physical body. Those who succeeded in this acquire the ability to control matter, as it was demonstrated by Jesus Christ, Babaji and Others [11,14]; today it is demonstrated by David Copperfield and Sathya Sai Baba.
