THE FOURTH SECTION OF THE DABISTAN contains an account of the Jamshaspian sect. The _Yekanah-binan_, “seers of unity,” also called the Jamshaí, who form another great body of the Parsees, are the followers of _Jamshasp_, the son of _Jemshid_, the son of _Tahmúras_: in their speech there is much that is enigmatical, and endless subtilty. Jamshasp never invited any one to follow his tenets, but he was of such exemplary life and so great a sage, that the people bore him great affection, and wrote down his sayings, until by degrees great numbers voluntarily adopted them as articles of faith. According to them, the world has no external existence; they hold that whatever exists is God, and that naught exists besides him: a holy man has said: “Every eye which is directed to the primitive nature, Unless tinged with the collyrium of divine light, Whatever it beholds in the world, except thy face, Is but the second image of distorted vision.” They hold that all the intelligences, souls, angels, heavens, stars, elements, the animal, vegetable, and mineral kingdoms exist within his knowledge, and are not external to it: which sentiment king Jamshid explained to Abtin, saying: “Know, O Abtin, that the Almighty conceived in idea the first intelligence; in like manner the first intelligence conceived three objects, namely, the second intelligence, the soul of the upper sphere, and the body of the same heaven: in like manner, the second intelligence conceived three objects, and so on in succession to the elements and their combinations: and this is exactly as when we form an idea of a city, with its palaces, gardens, and inhabitants, which in reality have no existence external to our imagination; so that, consequently, the existence of this world is of the same description.” The Abadian regard these sayings as enigmatical, although Jamshid composed many philosophical works, which the Yekanah Binan admit without any commentary: many of the Parsees adopt this creed, and particularly the ascetics of that class. The belief of these sectaries is illustrated by the following tetrastich from Subahani: “The sophist, who has no knowledge of intellect, Asserts that this world is altogether an optical illusion, In truth, the world is an illusion; however, Certainty is for ever displaying her effulgence there.” On this subject they have composed various works, the most celebrated of which is, the “Testament of Jamshid addressed to Abtin,” compiled by _Farhang Dostoor_. _Shídah_, _Suhráb_, _Mízan_, and _Jamshásp_, who, under the profession of mercantile pursuits, travelled along with _Shídósh_, the son of _Anósh_, were of the Yekanah Binan sect.
