“This mastic was also invented by a certain being with good Reason who belonged to one of the old Asiatic communities.
“The use of chewing this keva consists in this, that by chewing it, much what is called there on Earth ‘saliva’ and also other substances are formed in beings, which are worked out by their planetary bodies so that their first being-food may be the better and more easily transformed in them, or as they themselves say, so that this food may be the better and more easily ‘digested and assimilated.’
“Thanks to this keva their teeth are also strengthened and the cavities in their mouths too are cleaned from the remains of the first food; the use of keva is very necessary for your favorites, particularly for this second purpose, as these remains, not decomposing owing to the chewing of keva, do not give off that disagreeable ‘odor’ from their mouths which has already become proper particularly to the contemporary three-brained beings there.
“And the second custom, namely, the washing at times in special rooms of theirs called the ‘hammam’ was also invented by a certain ancient Asiatic being.
“In order clearly to understand the necessity for this second custom in the process of the existence of terrestrial beings, the following must be first explained to you.
“The functioning of the planetary body of beings of all forms of external coatings is adapted by Nature in general in such a way that the process of their nourishment with the second being-food, which your favorites call ‘breathing of air,’ proceeds in them, and this nourishment is taken in not only through the organs of breathing, but also through what are called the ‘pores’ present in their skin.
“Through the ‘pores’ of the skin of the beings, not only the new second being-food enters, but also through several of these pores, after the transformation of this second being-food, those parts of this food are given off from the skin which are either no longer necessary for the planetary body of the beings or which are already the result of its transmutation.
