No, the only things that follows logically is that not being judgemental is something that you can't teach someone else directly without judging yourself.

The zen monk that sits in his monastery can be happy and accepting of everyone who visits him.

Explaining what it means to not passing judgment to someone who never experienced it is like telling a blind person about the colors of the rainbow. If you talk about something being blue they don't mean what you are talking about.

If you ask the zen monk to teach you how to be nonjudgmental he might tell you that he's got nothing to teach. He tell you that you can sit down when you want. Relax a bit.

After an hour you ask him impatiently: "Why can't you help me?" He answers: "I have nothing to teach to you."

Then you wait another two hours. He asks you: "Have you learnt something?" You say: "Yes". You go home a bit less judgmental than when you were at the beginning.
