The one who encompasses all of these beliefs and knows their sources and origins and does not miss anything of them, then such a person does not have integrity because he does not see an opposite to this state that distinguishes this state because he is in it, and the universe, if it is in a thing, cannot be perceived by the eye or the vision of sight, even if it is known by it. Just as the air cannot be perceived due to excessive proximity, likewise the truth cannot be perceived due to excessive proximity, for it is closer to us than our jugular vein, so the eyes cannot perceive it.
