As true as Buddha's nature, it is not cosmic, and it is troublesome and dusty. It has no phase, how to wash it off? How to explain this sentence, please give me some advice.

Contact the expert to answer, this is my understanding:

Besides, it is really a Buddha, and naturally it is not an ordinary form, so mental troubles and physical dust can't be contaminated. Without a true image, how can I put my mistakes and doubts on the surface of the water and think that it has not cleaned myself for me?

In other words, really like Buddha, you don't have to bathe monks; If there is no Buddha nature, there is no bathing, and you can't blame yourself for not taking a shower.
