What does it mean that the meek shall inherit the earth?

Humility is a lesson for the ego, not for the spirit. Spirit is beyond humility, because it recognizes its radiance and gladly sheds its light everywhere. The meek shall inherit the earth because their egos are humble, and this gives them truer perception. The Kingdom of Heaven is the spirit’s right, whose beauty and dignity are far beyond doubt, beyond perception, and stand forever as the mark of the Love of God for His creations, who are wholly worthy of Him and only of Him. Nothing else is sufficiently worthy to be a gift for a creation of God Himself. T-4.I.12:2 - 6

What does it mean in the beatitudes when Jesus says that the meek shall inherit the earth? It is taught in A Course In Miracles that this saying means that the person has eschewed their ego in favor of Spirit.

In Alcoholics Anonymous it is suggested, in step three, that we give up our willfulness in favor of the will of God. This means being humble and setting our egos aside.

In Unitarian Universalism we covenant together to affirm and promote the inherit worth and dignity of every person. This inherent worth and dignity does not arise from the person’s ego, but rather from the Divine Spark within.

Today, it is suggested that we become meek and choose the Spirit over the ego in all our dealings and activities.
