Fulou honour person said, because of knowing the tongue, it is smooth. Manjusri Bodhisattva commented that the knowledge of the tongue is nothing more than playing with sound and language. You, Flouna, have made today's arhat, and it took a very long time to achieve eloquence. It is not a temporary function of tongue knowledge. It is a way of doing things with tongue knowledge, not a way of not missing inaction. How to achieve inaction by doing the right thing?
Amitabha!
