The meaning of this sentence is also very easy to understand. Buddha is a monk, and Tao is a Taoist priest. The general meaning is that in times of trouble, no monks can be seen. These monks are hidden in their own temples. On the contrary, what can be seen are these Taoist priests; but in times of prosperity, the Taoist priests disappear and the monks disappear. There are more of them.
There is a reason for this, that is, it is Taoist priests who appear when people need help, and these monks will come out when people do not need help.
This situation is also very common, even now, it is also a time of peace and prosperity. It can be said that there are many temples, and often these temples have some fat heads. The monks who listen to you will then ask you for some sesame oil money, and you must happily hand over your money to these monks.
We can now also find that these monks often have bad news. For example, the monk drives a Mercedes-Benz or a BMW and engages in corruption. It can be said that there is very little bad news about Taoist priests, or even basically none. Since ancient times, apart from those eminent monks or ascetics, they have always looked like this. It is not surprising that some people dislike these monks.
What Taoist priests pursue is basically immortality. If you want to live forever, you naturally need practice and merit. So in the peaceful and prosperous times, he used Taoist cultivation methods to cultivate himself in his own Taoist temple. Then once encountering troubled times, Taoist priests need to go down the mountain, save the world and save people, and add their own merits. Saving the world is what Taoist priests pursue.
Of course? Buddha is not seen in troubled times, and Tao is not seen in prosperous times? This sentence must be said by someone who likes Taoism, and he will definitely praise the goodness of Taoism. If he were a Buddhist, he would definitely devalue Taoism and promote Buddhism.
