Ruach: the "Holy Spirit"

Definition of "ruach" from Anne Robertson:

When I read the word "wind" I always want to look back to Hebrew for one of my favorite words, ruach, which is what this word is. It means wind, breath, spirit. It's the word ruach that Genesis 1 talks about hovering over the waters at creation and bringing things to life. It's the ruach that God breathed into Adam and Eve, giving them life. It was the ruach that brought life to Ezekiel's valley of dry bones. The wind that blows away the chaff and leaves the mature grain is the breath of God. Notice that it doesn't single out the wicked for fiery breath. It doesn't breathe especially easy on the righteous either. The same ruach blows across the threshing floor of the full heads of grain and the empty ones. But the wicked haven't grown. They haven't matured. They have no substance. They are merely shells, and when that wind blows, it blows them away.
