Meta. A sharp, piercing, perceiving, unyielding phase of consciousness, in the faculties in man that are represented by Judah, Ephraim, and Levi (stiff, rigid, hard, thorn, hard look, close watch, cities in the hill country of Judah and of Ephraim, and a Levite). These thoughts are always to the point, and do not prevaricate (sharp point); hence when they take sides with Truth they are approved by our higher consciousness and are very useful in overcoming error.
