Ones grasp of "reality" is based upon perception. Ones perception is filtered by ones own mind. It will grasp reject and filter to protect the self. Humans have developed many complexes to survive. These complexes have emerged in response to suffering, to protect oneself. We build the wall around our minds to protect our selves from reality(To protect ourselves from suffering). We become less and less aware untill we are nothing but a habit riden consciousness. This essentialy is suicide. These painfull hysterics emerges from abandoning our equilibrium. Hence those hysterics seperate us from "reality". Searching for truth when one is hysterical is comparable to running a marathon on crutches. It is esentially menatal retardation. To abandon inner balance is to render oneself uneffective and witless. Since inner balance and inner peace are the same thing, on the search for truth inner peace is essential.
