This is the truth intended to be expressed in the Mysteries. Sallustius, the neo-Platonic philosopher, in his treatise Peri Theon kai Kosmou, "Concerning the gods and the existing state of things," explains the rape of Persephone as signifying the descent of the soul. Other writers have explained the real element of the Mysteries as consisting in the relations of the universe to the soul, more especially after death, or as intimating obscurely by splendid visions the felicity of the soul here and hereafter when purified from the defilements of a material nature. The intention of all mystic ceremonies, according to Sallustius, was to conjoin the world and the gods. Plotinus says that to be plunged into matter is to descend and then fall asleep. The initiate had to withstand the dæmons and spectres, which, in later times, illustrated the difficulties besetting the soul in its approach to the gods, so also the Uasarian had to repel or satisfy the mystic crocodiles, vipers, avenging assessors, dæmons of the gate, and other dread beings whom he encountered in his trying passage through the valley of the shadow of death. Pindar, speaking of the Eleusinian Mysteries, says: "Blessed is he who, on seeing those common concerns under the earth, knows both the end of life and the given end of Jupiter."
Psyche is said to have fallen asleep in Hades through rashly attempting to behold corporeal beauty, and the truth intended to be taught in the Eleusinian Mysteries was that prudent men who earnestly employed themselves in divine concerns were, above all others, in a vigilant state, and that imprudent men who pursued objects of an inferior nature were asleep, and engaged only in the delusion of dreams; and that if they happened to die in this sleep before they were aroused they would be afflicted with similar, but still sharper, visions in a future state.
Matter was regarded by the Egyptians as a certain mire or mud. They called matter the dregs or sediment of the first life. Before the first purification the candidate for initiation into the Eleusinian Mysteries was besmeared with clay or mud which it was the object of the purification to wash away. It also intimated that while the soul is in a state of servitude to the body it lives confined, as it were, in bonds through the dominion of this Titanic life. Thus the Greeks laid great stress upon the advantages to be derived from initiation. Not only were the initiates placed under the protection of the State, but the very act of initiation was said to assist in the spreading of goodwill among men, keep the soul from sin and crime, place the initiates under the special protection of the gods, and provide them with the means of attaining perfect virtue, the power of living a spotless life, and assure them of a peaceful death and of everlasting bliss hereafter. The hierophants assured all who participated in the Mysteries that they would have a high place in Elysium, a clearer understanding, and a more intimate intercourse with the gods, whereas the uninitiated would for ever remain in outer darkness. Indeed, in the third degree the epoptæ were said to be admitted to the presence of and converse with the goddesses Demeter and Persephone, under whose immediate care and protection they were said to be placed. Initiation was referred to frequently as a guarantee of salvation conferred by outward and visible signs and by sacred formulæ.
The Lesser Mysteries were intended to symbolize the condition of the soul while subservient to the body, and the liberation from this servitude, through purgative virtues, was what the wisdom of the Ancients intended to signify by the descent into Hades and the speedy return from those dark abodes. They were held to contain perfective rites and appearances and the tradition of the sacred doctrines necessary to the perfection or accomplishment of the most splendid visions. The perfective part, said Proclus, precedes initiation, as initiation precedes inspection.
"Hercules," said Proclus also in Plat. Polit., "being purified by sacred initiations and enjoying undefiled fruits, obtained at length a perfect establishment among the gods"; that is, freed from the bondage of matter ascending beyond the reach of its hands.
Plutarch wrote:—
"To die is to be initiated into the great mysteries,... Our whole life is but a succession of errors, of painful wanderings, and of long-journeys by tortuous ways, without outlet. At the moment of quitting it, fears, terrors, quiverings, mortal sweats, and a lethargic stupor come and overwhelm us; but, as soon as we are out of it, we pass into delightful meadows, where the purest air is breathed, where sacred concerts and discourses are heard; where, in short, one is impressed with celestial visions. It is there that man, having become perfect through his new initiation, restored to liberty, really master of himself, celebrates, crowned with myrtle, the most august mysteries, holds converse with just and pure souls, and sees with contempt the impure multitude of the profane or uninitiated, ever plunged and sinking itself into the mire and in profound darkness."
Dogmatic instruction was not included in the Mysteries; the doctrine of the immortality of the soul traces its origin to sources anterior to the rise of the Mysteries. At Eleusis the way was shown how to secure for the soul after death the best possible fate. The miracle of regeneration, rather than the eternity of being, was taught.
Plato introduces Socrates as saying: "In my opinion those who established the Mysteries, whoever they were, were well skilled in human nature. For in these rites it was of old signified to the aspirants that those who died without being initiated stuck fast in mire and filth; but that he who was purified and initiated should, at his death, have his habitation with the gods."
Plato, again, in the seventh book of the Republic says: "He who is not able by the exercise of his reason to define the idea of the good, separating it from all other objects and piercing as in a battle through every kind of argument; endeavouring to confute, not according to opinion but according to evidence, and proceeding with all these dialectical exercises with an unshaken reason—he who cannot accomplish this, would you not say that he neither knows the good itself, nor anything which is properly demonstrated good? And would you not assert that such a one when he apprehended it rather through the medium of opinion than of science, that in the present life he is sunk in sleep and conversant with delusions and dreams; and that before he is roused to a vigilant state he will descend to Hades, and be overwhelmed with sleep perfectly profound?"
