The meaning of this passage is literal. During the boom, monks plundered money in various ways. Gone with the world closed the door and took refuge with the money found in the prosperous times. In troubled times, that is, chaotic and unstable times, Taoist priests will choose to go down the mountain to save people. In troubled times, their only idea is to save people. They didn't hesitate. Like the police in today's society, they maintain social order. They are fighting bandits and protecting the people. When everything was calm, they returned to the mountains and lived a quiet life. Why is there a saying that "a monk in prosperous times is a Taoist in troubled times"? During the War of Resistance against Japanese Aggression period, most Taoist priests went down the mountain to help us resist Japan. Monks without force will only close the door and "coexist peacefully" in the temple.
During the War of Resistance against Japanese Aggression period, Li led a group of Taoist priests in the mountains, who threw themselves into the front line of the war without hesitation and died for the country. Other Taoist priests also fought the enemy with the necromancer. In addition to them, there are many Taoist priests who went down the mountain to give their lives for their country. Their actions are amazing and worth learning.
On the other hand, as far as I know, many monks became traitors for money and desire during the Anti-Japanese War! In today's vigorous and peaceful society, there are more and more monks. Some behaviors of these monks have aroused great concern in society. Monks can enter and leave the temple at will. Even drink and eat meat, get married and have children. Monks even became a profession. Some people pay them to drink and eat meat in places where people burn incense. Earn enough money to go down the mountain, and then go back when the money is spent.
Therefore, it is very practical to say that there will be "monks in prosperous times and monks in troubled times".
