There is an opinion that saying hello through the doorstep, standing on it or doing anything else is a very bad omen. Its roots go back to antiquity and, what is noteworthy, there is not only the Slavic peoples, but also the Romans, some Muslim peoples. It is often difficult for many people to explain why the truth can not be greeted through the threshold , although the explanation lies on the surface, it is enough to go deeper into history.
Something common
The original logic is simple: if the walls and roof in the house are protected inside, then through the doorways into it can get any, not only light, air and guests. In this case, the threshold serves as a kind of continuation of the wall, blocking the path to bad energies.
Also, the threshold elementally fences the inside of the dwelling from the street, so the hand stretched from the outside can be regarded as an insult, because there is a reluctance of a person to work hard and enter inside even for a minute. That's why people do not greet through the threshold and, if necessary, simply go outside, for example, to receive a parcel from the courier.
Spirits of ancestors and brownies
In the time of paganism, it was a tradition to dig in the ashes of the ancestor, the former and the first master of the house, under the threshold. Thus, the house seemed to acquire a patron and defender in one person, who guarded the peace of the household from evil and not friendly forces.
If a person did not cross traits, but at the same time greeted or something took over the threshold, the protection of the first owner of the house fell and the premises became vulnerable to dark forces. Sitting or standing on the doorstep was considered an insult to the guardian of Rod, who because of this could become angry and stop guarding the house and its inhabitants. That's why you can not even shake hands by the door.
According to another version, which was also sacredly revered in ancient times, the threshold was considered the abode of a brown-haired man, who is a capricious creature and can easily bludgeon his masters or stop helping to trouble his house. Therefore, if you do not want to harm the owners, you can not in no way say hello through the doorstep or stay in the doorway.
Other crops
In ancient Romans the threshold was dedicated to the goddess of chastity - Vesta. Some Muslim peoples, on the contrary, believed that beneath it inhabited by evil genies and wake them undesirable.
In Mongolian and Slavic tribes, it was generally considered an insult to the home, and why there was a sign that you can not greet through the threshold.
