The mind wants to land, to fixate, to hold a concept, but the only way you can be really free is by not fixating. That's part of true maturity, and it's one of the hardest things for spiritual people who have had true and powerful revelations to go through - to accept the degree of surrender needed to literally let go of all experience and all self-reference. Even in great revelations, there is almost always something that wants to claim, "I am this." Every time you claim, "I am this", you just claimed another sense perception, thought, emotion, or feeling.
