'Reason' in the Bible

"But at the end of {that period}, I, Nebuchadnezzar, lifted up my eyes to heaven, and [then] my reason returned to me; and I blessed the Most High and {the one who lives forever} I praised and I honored. "For his sovereignty [is] [an] everlasting sovereignty, and his kingdom [continues] from generation to generation.

"{At that time} my reason returned to me, and [also] the glory of my kingdom and my majesty and splendor returned to me, and my advisers and my lords searched [me] out, and I was established over my kingdom and abundant greatness was added to me.
