A soul, upon leaving the body, in course of time found its way back to earth, surrounded by conditions suited to its stage of growth. Here it must reap all the consequences of its former life. It must also during its stay on earth make the conditions for its next appearance upon an earthly plane. So soon as through a succession of births and deaths it had perfected itself, it entered into a state of Nirvana. It was absorbed into the great Universal Soul. Nothing is ever lost. "Many a house of life Hath held me--seeking ever Him who wrought These prisons of the senses, sorrow fraught; Sore was my ceaseless strife! But now, Thou builder of this tabernacle--Thou! I know Thee. Never shalt Thou build again These walls of pain, Nor raise the roof-tree of deceits, nor lay Fresh rafters on the clay; Broken Thy house is, and the ridge-pole split! Delusion fashioned it! Safe pass I thence--deliverance to obtain."(60) 60) Edwin Arnold, The light of Asia. Regarding the opinions of the ancients on the subject of the eternity of matter, Higgins, in his learned work on Celtic Druids, says: "The eternity of matter is a well known tenet of the Pythagoreans, and whether right or wrong there can be no doubt that it was the doctrine of the oriental school, whence Pythagoras drew his learning. It was a principle taken or mistaken from, or found amongst, the debris of that mighty mass of learning and science of a former period, of which, on looking back as far as human ken can reach, the most learned men have thought that they could see a faint glimmering. Indeed, I think I may say something more than a faint glimmering. For all the really valuable moral and philosophical doctrines we possess, Dutens has shown to have existed there." From what is known relative to the speculations of an ancient race, the fact is observed that creation was but a re-formation of matter. Wisdom, or Minerva, formed the earth and the planets; she did not create the heavens and the earth, as did the later Jewish God. Of the seven principles of the universe, matter was the first, and of the seven principles of man, the physical body was the earliest. Through evolutionary processes, or through cyclic periods involving millions of years, mind was developed, and in course of time spirit was finally manifested.
