The word "accretion" appears only twice in all of the writings of Mary Baker Eddy. But it is a mighty word in spiritual instruction. As used by our Leader, Mrs. Eddy, it exposes the false tendency of trying to help ourselves or others by external addition. "Accretion" is a product of mortal mind's limited, false approach to substance.
The Master, Christ Jesus, made this profound statement for all mankind: "The kingdom of God is within you." Luke 17:21; The understanding that answers every mortal problem must be awakened from within consciousness. Understanding is not a thing to be added to oneself. The true nature of everyone for all time is man's reflection of the substance of Spirit, God, who is present always.
Awakening to the kingdom within and letting it unfold in our daily living is the direct path to spirituality. The word "unfoldment" denotes something coming from within. Waiting or struggling for good to come from a so-called outside source is the way of materiality.
