Generally speaking, it is recommended to provide a sacred position in the upper position, that is, the position that can be seen at a glance when you open the door. Of course, the actual situation can be flexibly mastered according to your actual decoration, and the harmony between Buddhism and law is possible. Every door, the first thing people see when they come in, is the big position, that is, the upper position. Because the building of the house faces different directions, no matter which direction, it is necessary to worship the Buddha in the upper position, not to engage in the southeast and northwest. That's right.
The young man who is good at money and knowledge in Hua Yan Jing visited the south. This "south" is definitely not the south of the southeast and northwest. What if only the south has good knowledge, while the north, the east and the west have no good knowledge? Why did all the good knowledge go to the south? "South" is a representation, representing light. Among the five elements, south is fire, fire represents light, and light represents wisdom. Good knowledge is a wise man. Where he lives, that place is called "South". Good learning is a man with good fortune, and the place where he lives is also called "Fucheng". Therefore, Fucheng and the south do not refer to one direction or one region. We should understand the meaning of Buddhism.
