the brightness or ethereal matter surrounding a deity
Greetings, friend @lakshmi,
Actually, this is the word:
Pneuma (πνεῦμα) is an ancient Greek word for "breath", and in a religious context for "spirit" or "soul". - Wikipedia. You can find somewhat more of a definition here with lots of references.
I chose "wind" as the word that I wanted my readers to "hear," because it's pretty clear from what Jesus was saying that "wind" is the strong image he is using to characterize God's nature. The wind blows wherever it wants to, and we can "hear" it and feel its effects, but cannot "see" it. This is analogous to God. He does whatever he wants, and we can sometimes perceive the effects of God's actions but can't necessarily "see" the details or the rationale.
thank you, yes, I get it!
