So it is said that we ought to go washed to sacrifices and prayers, clean and bright; and that this external adornment and purification are practiced for a sign. Now purity is to think holy thoughts. Further, there is the image of baptism, which also was handed down to the poets from Moses as follows:--
"And she having drawn water, and wearing on her body clean clothes." [2893]
It is Penelope that is going to prayer:--
"And Telemachus,
Having washed his hands in the hoary sea, prayed to Athene." [2894]
It was a custom of the Jews to wash frequently after being in bed. It was then well said,--
"Be pure, not by washing of water, but in the mind."
For sanctity, as I conceive it, is perfect pureness of mind, and deeds, and thoughts, and words too, and in its last degree sinlessness in dreams.
And sufficient purification to a man, I reckon, is thorough and sure repentance. If, condemning ourselves for our former actions, we go forward, after these things taking thought, [2895] and divesting our mind both of the things which please us through the senses, and of our former transgressions.
