The earth was without form and a void.
Have you ever been with a child that just started to walk about and his or her
curiosity is heightened? Every time, they view a new object and say, "what's that?"
"What's this?"
Then your own curiosity is awakened as you answer the child's question. It is as if your voice brings things out of the shadow into light.
"Why, that's a stone. That's a tree. That's a train."
You are essentially bringing things out, naming things, or reviewing names with the child. If you haven't ever been in a teaching mode, perhaps, you've never seen the faces light up when they learn a new thing in a space of time, or a space of a moment. The child never tires of being a new learner and finally, one day, the questions stop coming. They are more or less aware of things, and it is as a natural state to know what a thing is.
Do you ever lose a sense of wonder about things, how they came to be, how they were named? Who revealed the sacred names for things to you or your children?
It's called a voice.
