Equiano spoke of purification

From the text:

"I have before remarked that the natives of this part of Africa are extremely cleanly. This necessary habit of decency, was with us a part of religion, and therefore we had many purifications and washings; indeed almost as many, and used on the same occasions, if my recollection does not fail me, as the Jews. Those that touched the dead at any time were obliged to wash and purify themselves before they could enter a dwelling-house. Every woman, too, at certain times was forbidden to come into a dwelling-house, or touch any person, or any thing we eat. I was so fond of my mother I could not keep from her, or avoid touching her at some of those periods, in consequence of which I was obliged to be kept out with her, in a little house made for that purpose, till offering was made, and then we were purified."
