In detail, even if you have sex with your wife, there are differences in time, place and place, and violation of these contents is also included in a certain degree of lewdness.
In addition to not having sex during the day, there are also some specific Buddhist festivals, such as Buddhist monks and bodhisattvas' becoming monks, attaining enlightenment and nirvana, as well as several specific days in the month. In addition, special astronomical conditions such as rain, snow and thunderstorms are also taboo days. These dates are not suitable for sex except for their specific significance, from the perspective of scientific health preservation.
Place means that it is not suitable to commit adultery anywhere except the couch. As for the holy places such as temples and Buddhist temples, it is very sinful to commit adultery!
generally speaking, the part refers to adultery in non-private parts (such as anal sex, oral sex, etc.), and in addition, posture inversion, etc., also belongs to this category.
Similarly, homosexual, voyeuristic, bestiality and other improper sexual behaviors naturally belong to the category of lewdness.
In fact, the requirements for normal sex are recognized not only in Buddhism, but also in the etiquette of Confucianism and Taoism. In the traditional state religion, it is believed that playful and improper sexual intercourse, once pregnant, has great side effects on implantation and fetal genes. Even in TCM health care, there are many original insights on the relationship between sexual life and fertility.
The question of whether Buddhist thoughts can' keep pace with the times' is a topic involving too much information. Generally speaking, Buddhism will not stick to the rules (and there is no' rule' against it) in terms of being beneficial to human body and mind and the fundamental development of social harmony, because such a tone is the basic idea of benefiting all beings in Buddhism. If we satisfy the abnormal development of people's extravagant desires and adapt to the increasingly expanding material desires of society, it is contrary to the Buddhist thought of purity and peace, and naturally we will not cater to it.
Facts have proved that some improper social and human progress (for example, excessive emphasis on industrial development and neglect of environmental protection and resource protection, etc.) will often come to realize how correct and wise the teachings of Buddhism and even our ancestors' saints are to be pure and indifferent to fame and fortune and return to nature.
in a word: wisdom is unique and unchangeable, and will not be limited by time and space conditions. It is not the attribute of wisdom that can make it change.
