Metaphysical meaning of leaven (rw)
leaven--The leaven is the Truth. "The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till it was all leavened" (Matt. 13:33). When a word of Truth seems to be hidden in the mind, it is not idle but is quietly spreading from point to point. This process continues until the whole consciousness is vitalized by Spirit.
"Take heed, beware of the leaven of the Pharisees and the leaven of Herod" (Mark 8:15). In this case, the leaven represents limited thoughts. When we attempt to confine the divine law to the customary avenues of expression and scoff at anything beyond, we are letting the leaven of the Pharisees work in us. When we allow the finer forces of the body to fulfill lust and appetite, we are letting the leaven of Herod work to our undoing.
