“The doctrine of the Essens is this: That all things are best ascribed to God. They teach the immortality of souls, and esteem that the rewards of righteousness are to be earnestly striven for; and when they send what they have dedicated to God into the temple, they do not offer sacrifices because they have more pure lustrations of their own; on which account they are excluded from the common court of the temple, but offer their sacrifices themselves; yet is their course of life better than that of other men; and they entirely addict themselves to husbandry. It also deserves our admiration, how much they exceed all other men that addict themselves to virtue, and this in righteousness; and indeed to such a degree, that as it hath never appeared among any other men, neither Greeks nor barbarians, no, not for a little time, so hath it endured a long while among them. This is demonstrated by that institution of theirs, which will not suffer any thing to hinder them from having all things in common; so that a rich man enjoys no more of his own wealth than he who hath nothing at all. There are about four thousand men that live in this way, and neither marry wives, nor are desirous to keep servants; as thinking the latter tempts men to be unjust, and the former gives the handle to domestic quarrels; but as they live by themselves, they minister one to another. They also appoint certain stewards to receive the incomes of their revenues, and of the fruits of the ground; such as are good men and priests, who are to get their corn and their food ready for them. They none of them differ from others of the Essens in their way of living, but do the most resemble those Dacae who are called Polistae [dwellers in cities].”

Upon the Sovereign Sun (362)
Context: Inasmuch as it is my wish only to compose a hymn of thanksgiving in honour of the god, I have deemed it quite sufficient to discourse to the best of my ability concerning his nature. I do not think I have wasted words to no purpose: the maxim, "Sacrifice to the immortal gods according to thy means," I accept as applying not merely to burnt-offerings, but also to our praises addressed unto the gods. I pray for the third time, in return for this my good intention, the Sun lord of the universe to be propitious to me, and to bestow on me a virtuous life, a more perfect understanding, and a superhuman intellect, and a very easy release from the trammels of life at the time appointed: and after that release, an ascension up to himself, and an abiding place with him, if possible, for all time to come; or if that be too great a recompense for my past life, many and long-continued revolutions around his presence!

Context: I do not wish by what I have said to raise any exaggerated expectations as to the worth of these ancient hymns of the Veda, and the character of that religion which they indicate rather than fully describe. The historical importance of the Veda can hardly be exaggerated; but its intrinsic merit, and particularly the beauty or elevation of its sentiments, have by many been rated far too high. Large numbers of the Vedic hymns are childish in the extreme: tedious, low, commonplace. The gods are constantly inyoked to protect their worshippers, to grant them food, large flocks, large families, and a long life; for all which benefits they are to be rewarded by the praises and sacrifices offered day after day, or at certain seasons of the year. But hidden in this rubbish there are precious stones.
