Dunhuang Caves, China
Talking about the rise and fall of Mogao Grottoes with secular speculation is not enough to profoundly verify its internal meaning.
Instead, the classic works of Buddhism itself can explain all these meanings.
In his important book "Vajra Sutra", Shakyamuni talked about his true views on the object image,
and warned future generations not to be greedy for the surface of the object image,
or even the appearance of the doctrine, so that true wisdom and freedom can be obtained.
The excavations of these caves were made by local gentry,
for the prosperity of the family, but history has responded to their prayers at a very fast rate.
Under the ruins, these people at that time did not know where they had gone, nor did the world Continue as they hoped.
