In the Tenth Step (Capricorn), the Father and Mother reintegrate the World, and all Their Expansions and parcels, in Themselves. They are Alone again, with the Memory of having been all of Their Manifestations, down to Their human parcels, and simultaneously with Their own Memory of He and She, the Original Person.
The Memory of Their Manifestation is more than a mere remembrance. Actually, though in the Curve of Time it reintegrates Them in the Tenth Step, it is eternal, as the whole Eternal Book is eternal. Also, the Dimension of the Renewed Human Being who has reintegrated Them is now totally infused in Themselves, not in a differentiated manner, but as a "living imprint". And it is in this "New Form" that They live the two final Steps, the Conclusion of Their Eternal Book.
