Show humility. Buddhism is cultivated from respect. Let go of arrogance and enter through a side door to show respect for the three treasures of Buddhism. Buddhism stipulates that everything is right-handed, and this name is auspicious. So it's best to enter through the left door and exit through the right door.

There are three gates at the entrance of the Buddhist temple, which are called "three liberation gates". That is an empty door, no way, no way. Therefore, becoming a monk is also called "escaping into an empty door". These three doors represent wisdom, compassion and convenience respectively.

This hall, also known as Vatican Palace or King of France Hall, looks like a palace, and the main entrance in the middle is taken by the emperor. Walking in the middle is like being an emperor, which is rude and proud.

But you can also take the middle door and think of yourself as the French king (Buddha). Buddha went this way, so did I. The Buddha became a Buddha, and I am not a Buddha. Buddha's interests help all sentient beings, and I will also help all sentient beings with interests. I am no different from Buddha. To do this, you can also take the middle door.
