While respecting spiritual beings, to keep aloof from them, may be called wisdom.

I think the Master was right.
Did the gods ever listen?
Did the deities ever act?
I do not know, do not know.
Don't want to get entangled
In their strange and divine games

To worship to other than one's own ancestral spirits is flattery

So true! For what does he care,
This distant God in Heaven.
Is this God my creator?
I do not know, do not know.
Should I bow and sacrifice
To one I have never seen?

While you are not able to serve men, how can you serve spirits?

There's so much evil on earth.
Man is incomprehensible.
I have never seen a ghost.
I do not know, do not know.
Let's not ponder about it,
For it only breaks my head.

What you know, you know, what you don't know, you don't know. This is knowledge.
