Offering a hand shake

In Israel, G-d is the source of all good and all benevolence that is brought down upon our lives in the form of Torah.
Existing in Israel is a status of life called shomer negiah.  Shomer Negiah is one who guards his touch.

Israel is a place where men and women coexist; however, men are a separate spiritual composition from that of women.
Men shake mens hands of course and that is of course the geniality and generosity that exists among men.
When a man is offered a womans hand to shake, however, women are not constitutionally (not the American Constitution, but the constitution of the innermost part of your being) the exact make up of a man.  Women exist in a different spiritual milieu and of course, if a man is to come into physical direct contact with a woman in the sense that his skin touches hers, namely I believe his own hands palm and the surface of his neshama that conveys a bridge to the nations and peoples, his own spiritual connection is altered.  In the case of a man who is married or is a blood relative of a woman that he may shake hands; this spiritual connection is a true connection.

In the situation where a man shakes the hand of a woman whom he is not a blood relative; his connection to her spiritual milieu is established and it forms a bridge between the two people.  This may sound simple and even to many innocent overall, but it is actually a dangerous practice.

Today, there is much freedom in the world and the world of women and men is such that there is always business among each other as well as in todays day and age, a lapse in Torah Judgement among many of the people that exist in most of the communities today.

Men who shake the hands of a woman that is not a blood relative expose themselves to a slight situation whereby the bonds that they have among their blood relatives and of course married wife are conflicted with that of the unrelated woman that is in spiritual and physical contact with their touch.

It may seem zealous to a few, but I assure the readers that this is a practice that will not result in your undoing completely, but it will leave footprints of deceit in your heart.

There are however some instances where a man can and should shake the hand of a person of the opposite gender that I believe.
In the instance when a woman is your governor or your legislator, she is no longer spiritually an equal at the level of being a relationship that you simply would find to occupy your heart as a normally placed woman does indeed change your spiritual connections.
In fact, it is a blessing to shake the hands of your governors or legislators as they are responsible for your own protection and well being.
Another case is that of a physician or attorney who has a physician patient relationship or an attorney client relationship.  In this case it is my belief that you should indeed shake the hand of the opposite gender in this capacity so that they are indeed given the trust that you must extend in the office that you function.

When you are in the market place, it may be nearly impossible to avoid some physical contact with another woman as perhaps she is giving your a return or change or some other transaction. 
In this case, I disagree that one should be overly anxious about avoiding the contact, but one should position ones self so that physical contact is unlikely. 

In situations where you are a patient; there may be female providers and likely woman nurses and the like.  This does not pose a threat to a shomer negiah status as that is your health and safety that is at stake.  This is a tolerable situation and one should do what one must do to receive health care or other necessary treatments. 

Perchance that a woman is menstruating, this is an absolute contraindication for a man to touch a woman of course, including of course his own wife or children.

So this I hope is a guide by which a jew living in this day and age can attempt to be a guardian of the touch and bring about his own health and happiness in this world.
