Vijitâsva could make himself invisible. This may have reference to the state of the body at that stage of evolution. The fires appeared as it is they that give forms. The object corresponding to elemental fire is Rûpa or form. Barhishad, the name of one class of Pitris, was the progenitor of the form-producing Linga Sarira with all its potentialities. We find the senses developed in his sons the Prachetas brothers. "Pra" Means perfect and "Chetas" is the perceiving mind. But the mind perceives through the Indriyas, which are ten in number. Therefore they are ten brothers all alike; but they are wedded to one girl Mârishâ. There is some occult connection between water and sense perception. Barhishad was married to the daughter of the Ocean-god. The Prachetas brothers remained submerged for a thousand years in the waters. The protozoa and protophytes must of necessity be aquatic, as it were, for the development in them of sense perceptions. It is in Touch that the sense perceptions find a common basis. Touch underlies all other perceptions. It is touch of the object by one sense or other that gives rise to one perception or the other. "Kandu" is primarily scratching or itching, secondarily touch. Mârishâ was nourished by the moon and brought up by the plants. The period refers to the stage of evolution when the vegetables formed the predominant creation. It corresponds somewhat to the geological period of tree-ferns and lycopods in our Manvantara. The development of sense perceptions is the result of a communion with Vishnu, under the auspices of Rudra. This means a further infusion of Satva by Vishnu, which was made possible by the Dissolving influence of Śiva. And the son of the Prachetas brothers is verily Daksha, the Prajâpati of procreation, reincarnated under better auspices for the purpose of extending the creation. So we find the Trinity acting as three in one in the creative process. With the appearance of Daksha Jiva evolution comes to an end in the first Manvantara. TABLE V.
