The absence of unity is the characteristic of all primitive forms of religious thought; hence, the various differentiations mentioned above occur as a matter of religious necessity.
Among the practices prohibited by the Taoist religion: “A man must not sing and dance on the last day of the moon.... Must not weep, spit, or be guilty of other indecency towards the North.”—(Legge, “Religions of China,” p. 187.)
The Parsis have a curious idea suggestive of the Hebrew antagonism to the worship of Bel-Phegor: “14. The rule is that when one retains a prayer inwardly and wind shall come from below, or wind shall come from the mouth, it is all one.” (Shayast la Shayast, Max Müller’s edition, Oxford, 1880, cp. x. verse 14, p. 221. A footnote explains: “Literally, ‘both are one,’ that is, in either case the spell of the vag or prayer is broken.”)
“The Bedawi, who eructates as a matter of civility, has a mortal hatred to a crepitus ventris; and were a by-stander to laugh at its accidental occurrence, he would be at once cut down as a ‘pundonor.’ The same is the custom among the Highlanders of Afghanistan. And its artificial nature suggests direct derivation; for the two regions are separated by a host of tribes, Persians and Beloch, who utterly ignore the pundoner and behave like Europeans. The raids of the pre-Ishmaelitish Arabs over the lands lying to the northeast of them are almost forgotten; still, there are traces, and this may be one of them.”—(Burton, “Arabian Nights,” vol. v. p. 137.)
According to Niebuhr, the voiding of wind is considered to be the gravest indecency among the Arabs; some tribes make a perpetual butt of the offender once guilty of such an infraction of decorum; the Belludjages, upon the frontiers of Persia, expel the culprit from the tribe. Yet Niebuhr himself relates that a sheik of the tribe “Montesids” once had a contest of this kind among his henchmen, “avoit autorisé un défi dans ce genre entre ses domestiques et couronné le vainqueur.” (Niebuhr, “Description de l’Arabie,” Amsterdam, 1774, p. 27.) Snoring and Flatulence would seem to have been considered equally offensive by the Tartars. See Marco Polo’s reference to the mode of selecting wives for the Grand Khan (in Purchas, vol. i. p. 82). He says that the Grand Khan puts those deemed to be eligible under the care of “his Barons’ wives,” “to see if they snore not in their sleepe, if in smell or behaviour they bee not offensive.”
