to those entering the temenos (sacred precinct) of Eleusis the program was stated, not to advance inside the adytum. (Proclus, cited in Mylonas Eleusis and the Eleusinian Mysteries, p. 261)
In the most sacred Mysteries before the scene of the mystic visions, there is terror infused over the minds of the initiated. (Proclus, cited in Casavis The Greek Origins of Freemasonry. 111)
In Proclus’ commentary on the Timaios 293c, he offers another recitation. In the Eleusinian rites they gazed up to the heaven and cried aloud “rain,” they gazed down upon the earth and cried “conceive.” On the edge of a well by the Dipylon gate of Athens where the procession to Eleusis began, an inscription reads: O Pan, O Men, be of good cheer, beautiful Nymphs, rain, conceive, overflow. (Cited in Mylonas Eleusis and the Eleusinian Mysteries p. 270)

So too, there are men who are possessed and who receive a Divine Spirit. Some receive it spontaneously, like those who are said to be ‘seized by God’, either at particular times, or intermittently and on occasion. There are others who work themselves up into a state of inspiration by deliberate actions. When divine inspiration comes there are some cases where the possessed become completely besides themselves and unconscious of themselves. However, there are others where, in some remarkable manner, they maintain consciousness…However, when the loss of consciousness (ekstaseôs) is total, it is essential that someone in full command of his faculties assists the possessed. (Proclus Diadochus. On the Signs of Divine Possession.)
