What do you mean, quiet and profound?

Quiet and far-reaching is an idiom.

Pronunciation is níngj ngzhyu?n, which means that only when you are calm and focused can you accumulate wealth and make a difference. From Huainanzi: Main skill training.

Or: Only when you calm down and concentrate, can you accumulate wealth and make a difference. This sentence was first written by Liu An, a Taoist priest in the early Western Han Dynasty, and was also quoted by Zhuge Liang, the prime minister of Shu Han.

Quiet and far-reaching: a calm and quiet mind is not moved by other thoughts, and quiet reflection can establish (realize) lofty goals.

Zhuge Liang's "Commandment" said: "Indifference means no ambition, and tranquility is not far away." Ge Hong, a Taoist priest, said that "there is no self-restraint, and it is quiet and comfortable".

Quiet is a beautiful realm, peaceful and tranquil, like autumn water, reflecting the bright moon.
