To explain to themselves the existence of Evil and Suffering, the Ancient Persians imagined that there were two Principles or Deities in the Universe, the one of Good and the other of Evil, constantly in conflict with each other in struggle for the mastery, and alternately overcoming and overcome. Over both, for the SAGES, was the One Supreme; and for _them_ Light was in the end to prevail over Darkness, the Good over the Evil, and even Ahriman and his Demons to part with their wicked and vicious natures and share the universal Salvation. It did not occur to them that the existence of the Evil Principle, by the consent of the Omnipotent Supreme, presented the same difficulty, and left the existence of Evil as unexplained as before. The human mind is always content, if it can remove a difficulty a step further off. It cannot believe that the world rests on nothing, but is devoutly content when taught that it is borne on the back of an immense elephant, who himself stands on the back of a tortoise. Given the tortoise, Faith is always satisfied; and it has been a great source of happiness to multitudes that they could believe in a Devil who could relieve God of the odium of being the Author of Sin. But not to all is Faith sufficient to overcome this great difficulty. They say, with the Suppliant,_"Lord! I believe!"_--but like him they are constrained to add,_"Help Thou my unbelief!"_--Reason must, for these, co-operate and coincide with Faith, or they remain still in the darkness of doubt,--most miserable of all conditions of the human mind. Those, only, who care for nothing beyond the interests and pursuits of this life, are uninterested in these great Problems. The animals, also, do not consider them. It is the characteristic of an immortal Soul, that it should seek to satisfy itself of its immortality, and to understand this great enigma, the Universe, If the Hottentot and the Papuan are not troubled and tortured by these doubts and speculations, they are not, for that, to be regarded as either wise or fortunate. The swine, also, are indifferent to the great riddles of the Universe, and are happy in being wholly unaware that it is the vast Revelation and Manifestation, in Time and Space, of a Single Thought of the Infinite God.
