When the life wave has gone through all seven globes of the planetary chain, it has completed one planetary round or globe manvantara. This is followed by the dissolution of the planetary chain in a nirvana (which is not the same as what Buddhism calls nirvana because it is not permanent) or pralaya. Finally, a new round begins, in which consciousness is now more developed than in the preceding round.
Seven such planetary rounds (or forty-nine globe rounds) represents one kalpa or manvantara or day of brahma. This is followed by a higher "nirvana" or pralaya, which is the pralaya of that planetary chain. This lasts until a new planetary chain forms with its various life waves.
Seven such planetary chains and their pralayas constitute a solar manvantara, after which the solar system is dissolved in a cosmic pralaya, before the cycle begins anew.
According to Max Heindel's Rosicrucian writings about the scheme of evolution, in the beginning of a Day of Manifestation a certain collective Great Being, God, limits Himself to a certain portion of space, in which He elects to create a Solar System for the evolution of added self-consciousness. In God there are contained hosts of glorious Hierarchies and lesser beings of every grade of intelligence and stage of consciousness, from omniscience to an unconsciousness deeper than that of the deepest trance condition. During the current period of manifestation these various grades of beings are working to acquire more experience than they possessed at the beginning of this period of existence. Those who, in previous manifestations, have attained to the highest degree of development work on those who have not yet evolved any consciousness.
The period of time devoted to the attainment of self-consciousness and to the building of the vehicles through which the spirit in man manifests, is called "Involution". The succeeding period of existence, during which the individual human being develops self-consciousness into divine omniscience, is called "Evolution". Every evolving being has within him a "force" within which makes evolution not to be a mere unfoldment of latent germinal possibilities but a process where each individual differ from that of every other. This force, called "Epigenesis" provides the element of originality and gives scope to the creative ability which the evolving being is to cultivate that he may become a God.
Heindel states that in the Solar system, God's Habitation, there are seven Worlds differentiated by God, within Himself, one after another. These Worlds have each a different "measure" and rate of vibration and are not separated by space or distance, as is the earth from the other planets. They are states of matter, of varying density and vibration (as are the solids, liquids and gases of the physical Earth). These Worlds are not instantaneously created at the beginning of a day of Manifestation, nor do they last until the end. The evolutionary scheme is carried through five of these Worlds in seven great Periods of manifestation, during which the evolving virgin spirit becomes first human and, then, a God. The highest Worlds are created first, and as involution is to slowly carry the life into denser and denser matter for the building of forms, the finer Worlds gradually condense and new Worlds are differentiated within God to furnish the necessary links between Himself and the Worlds which have consolidated. In due time the point of greatest density, the nadir of materiality, is reached. From that point the life begins to ascend into higher Worlds, as evolution proceeds. That leaves the denser Worlds depopulated, one by one. When the purpose has been served for which a particular World was created, God ends its existence, which has become superfluous, by ceasing within Himself the particular activity which brought into being and sustained that World.
