Temples and Religion
Religion is taken very seriously in the Middle East; it’s always important to show due respect to religious buildings, shrines, images and people at prayer. When entering a mosque, remove your shoes and leave them at the door (socks are OK). In general women must cover their heads before entering the mosque and in some mosques a full length gown must be worn.
Dress
Middle Eastern people are very conservative about dress. Women are expected to dress modestly, with legs and shoulders covered. Trousers are acceptable, but shorts and short skirts are offensive to many. Men should always wear a shirt in public, and avoid shorts. Staying well-groomed and dressing respectably vastly improves the impression you have on the local people.
Other Possible Mistakes
Out of respect for the local culture, and for the cultures of other participants, kindly refrain from any unnecessary close contact and expressing of affection in public.
Use of Water
In the Middle East water, rather than toilet paper is used for cleaning oneself after going to the toilet. You will find that toilet facilities are generally reasonably clean and almost always have a tap and hose or mug for washing oneself. Washing with water cleans much better than toilet paper, is more hygienic, and cools the lower chakras at the same time. Afterwards you should, as with paper, wash your hands with soap. Rub the soap in the right hand (your clean hand), put back the soap, and clean the left hand with the right.  (Note: participants can carry their own supply of tissues if preferred)
