The Book of Ahkman

1And it was commanded of us that we should wash all those who desired to enter our group. And the washings were done by way of water. Now behold these washings were performed so that those who did unite with use were clean to begin anew. And we did also wash those priests who did to enter the sacred places of the Temple. And they were washed from head to foot and purified. And as part of their washing they were also anointed with sweet smelling perfumes. And they were anointed with oil. And they did wash in a lesser manner every time they did enter the temple.
