From that Kâlpic plane and the dweller thereof, we come to lower planes and their dwellers, to the divisions of time that rule the lives of individuals and of lives adapted to these divisions of time. We come from the elementals of the Svarga plane, or the Devas, to the elementals of the Astral or Bhuvar plane, the Pitris, Bhûtas, Pretas and Pisâchas, till we reach the mineral kingdom, represented by Himalya, the Mountain king. At this point a turning point was reached in life evolution, and the goddess of life-evolution became the daughter of the Mountain king. Of this we shall know more hereafter. We know of Daksha, first as the son of Brahmâ, the creative Prajâpati when the life-process rapidly worked itself out in Elemental forms. Then there was no sexual procreation. Creation meant the materialisation of the Jiva. Satî, the daughter of Daksha, was the guiding energy of life-evolution. She became wedded to Śiva, the Lord of Bhûtas, Pretas and Pisâchas who by the infusion of their Tâmasic energies could bring down Jivas from their high spiritual plane. When the process of materialisation was over, when the Jivas or Monads reached the lowest limits of materiality, the mission of Daksha came to an end. Life evolution had now to pass through mineral, vegetable and animal stages, until at last the human stage was reached. Satî now appeared as the daughter of the mineral king Himâlaya. She gave the upward bent to life evolution and by the energy she imparted minerals were able to shake off the rigidity and stability of gross matter, to develop the sense of touch and to become vegetable at last. In like manner vegetable became animal, and animals at last became men. Śiva, the husband of Bhagavati or Durgâ, as Satî was now called, is the Purusha of Dissolution. Bhagavati is His Energy, Who guides the Monadic or Jiva Evolution of the Kalpa. It is the wear and tear, the process of destruction, that counteracts the cohesive strength of the particles forming mineral matter, which by its action becomes flexible and so receptive of outside influences. Cells by division and death become capable of the life process in themselves. Vegetables grow by the rejection of cells, which necessitates a number of physiological processes. Death brings on life, waste, repair. If animals exist in one and the same body, progress will be limited, further evolution will be impossible. It is by death that we evolve. Bhagavatî works out the evolution of life in different kingdoms till the stage of humanity is reached. At this point Aryaman, one of the Âdityas, comes to the help of humanity. Through his influence the sons of humanity become endowed with the power of reasoning, — the faculty of discrimination.
