Can there be a wall opposite the pharmacist Buddha?

Yes, that's all right.

Buddha and Bodhisattva have great achievements, great compassion and boundless magical powers. If you need to sacrifice, you don't need to choose a date, time, feng shui and direction. There is no limit to "one Buddha breaks all evils". Therefore, there is no need to pay attention to orientation, you think it is good to put it solemnly; You don't need to choose the time. To be respectful, any time is a good time. This is what the so-called "sincerity is the spirit" means. As for the popular saying that pays attention to time and orientation, it is a common misunderstanding of Buddhism. Don't confuse faith with superstition and custom. It's just that there is a folk custom that the Buddha and Bodhisattva face the doors and windows, which means "open the door and see happiness", which is acceptable.

We ordinary people have no confidence in ourselves, so we need external things (such as statues, beads, pendants, etc.) to improve; If you really have a Buddha in your heart, it doesn't matter whether you have respect or not, because opening your eyes and closing your eyes are all Buddhas inside and outside your heart.
