The old ruling ego, threatened by a newborn light in the body, moves to destroy it while it is still small. Herod is the tyrant self that governs by fear and will kill any fresh awareness rather than surrender the throne. The children under the number 2 are the young spiritual impulses, still in their first duality and not yet grown strong; the reign of appetite slaughters them before they can mature.
This is the constant murder inside a person, where the settled lower nature crushes each rising insight that would unseat it.
Herod: the tyrant ego that rules by fear and destroys any new awareness that threatens its throne.
Bethlehem: the house of bread in the body, the humble inner place where the new light is born.
2 years old and under: the youngest spiritual impulses, still in early duality and too new to survive the lower nature's attack.
