The ESSENE GOSPEL OF PEACE - (about 30 paragraphs down from the beginning)

"Seek, therefore, a large trailing gourd, having a stalk the length of a man; take out its inwards and fill it with water from the river which the sun has warmed. Hang it upon the branch of a tree, and kneel upon the ground before the angel of water, and suffer the end of the stalk of the trailing gourd to enter your hinder parts, that the water may flow through all your bowels. Afterwards rest kneeling on the ground before the angel of water and pray to the living God that he will forgive you all your past sins, and pray the angel of water that he will free your body from every uncleanness and disease. Then let the water run out from your body, that it may carry away from within it all the unclean and evil-smelling things of Satan. And you shall see with your eyes and smell with your nose all the abominations, and uncleannesses which defiled the temple of your body; even all the sins which abode in your body, tormenting you with all manner of pains. I tell you truly, baptism with water frees you from all of these. Renew your baptizing with water on every day of your fast, till the day when you see that the water which flows out of you is as pure as the river's foam. Then betake your body to the coursing river, and there in the arms of the angel of water render thanks to the living God that he has freed you from your sins. And this holy baptizing by the angel of water is: Rebirth unto the new life. For your eyes shall henceforth see, and your ears shall hear.
