Full context:   Books one and two of the Logic are the doctrines of "Being" and "Essence." Together they comprise the Objective Logic, which is largely occupied with overcoming the assumptions of traditional metaphysics. Book three is the final part of the Logic. It discusses the doctrine of "the Concept," which is concerned with reintegrating those categories of objectivity into a thoroughly idealistic account of reality.[p] Simplifying greatly, Being describes its concepts just as they appear, Essence attempts to explain them with reference to opposites, and the Concept explains and unites them both in terms of an internal teleology. The categories of Being "pass over" from one to the next as denoting thought-determinations only extrinsically connected to one another. The categories of Essence reciprocally "shine" into one another. Finally, in the Concept, thought has shown itself to be fully self-referential, and so its categories organically "develop" from one to the next.
