Thorough Understanding of Theory Does Not Equal Empirical Validation

After studying any theory, one may come to understand it, grasp it, know it, and learn to apply it. One may become able to answer questions fluently, explain it to others, and articulate it clearly, achieving mental clarity.

However, does this equate to having actualized it? Does it equate to making the theory one's own knowledge and insight?

Achieving thorough familiarity with a theory is not difficult; neither is answering questions fluently or drawing inferences. What proves challenging is advancing to the stage of verification, proceeding step by step through actual realization. Yet the most difficult feat is to successfully navigate the stage of realization and truly attain it.
