There is One Single Thread Binding My Way Together in Chinese / Japanese...

吾道一以貫之 is a phrase from the Analects of Confucius that translates as “My Way has one thread that runs through it.”

Other translations include:
My Way is penetrated by a single thread.
There is one single thread binding my Way together.
My Way is run through with a unifying thread.
My Way is Consistent.
And sometimes poetic license is taken, and it is translated as:
My Way is the only one; I'll treasure it and stick to it with humility until the end.

After this was said, some 2500+ years ago, another disciple of Confucius clarified the meaning by stating, “Our master's Way is to be loyal and have a sense of reciprocity.”

In Japanese, this is purported to be romanized as “Waga michi ichi wo motte kore wo tsuranuku,” though some will argue the true pronunciation.

Note: Sometimes written 吾道以一貫之 instead of 吾道一以貫之 with no difference in meaning.
