What can not be done in the post?
Fasting is one-day and many days. One-day is Wednesday and Friday, as well as three fasts "in number" - the Exaltation, the day of the Beheading of St. John, and the Epiphany. Many days fasts four, Great, Petrovsky, Rozhdestvensky and Uspensky. There is an opinion that the posts only suggest abstinence in eating. But this is not so. Consider what you can not do in a post to conduct it correctly.
In the post you can not indulge in fun, walk onentertaining events, singing, having fun, dancing, attending concerts, film screenings, shows. It is also not recommended to organize holidays themselves, it concerns feasts for weddings, birthdays, anniversaries, housewarming, celebrating the passing of exams or getting diplomas, seeing off for the army and so on. It is forbidden to foul language, gossip.
In accordance with diet, during fasting alcoholnot prohibited, it is not of animal origin. But binge drinking is always associated with gay binge, so the priests do not recommend eating it during fasting. But if you drank a glass of vodka at a funeral feast, it is not forbidden. By the way, the church also considers smoking a sin, so during fasting it's time to quit this addiction.
The following requirement from the list of what can not bedo in the post, abstinence from sexual relations. In the modern world, this requirement is considered almost impracticable, but in prerevolutionary Russia it was strictly adhered to. This requirement is connected with the fact that during the fast there must be a liberation of the soul from everything that enslaves it. And sex is considered one of the dependencies that deprives a person of will.
