Creatures that drift
in the depths of the sea
are the very last
to discover the water
You are able to perceive voluminous space only because your mind fuses the two different perspectives received by your two eyes.
From one point of view, your inner eye sees merely plane images. In order to perceive solid structures in voluminous space, you must move around the subject under observation and fuse an indefinite number of aspects from all sides. A cone, for illustration, is seen as a circle in plan view, a triangle in elevation, and various angles subtended by various arcs in all other views. The solid structure of a cone is conceived only after fusing all images in the mind. If your mind were not able to construct this gestalt, you would be unable to recognize the triangular aspect of the cone as having the same identity as the circular aspect.
The ability to fuse an indefinite number of plane images into a solid image in the mind is usually achieved during childhood as we master language, so no one is aware of common aberrations. As an example, few people saw the view from the top until everyone traveled by air. Without flight experience, you don't learn to fuse plan views of the landscape with the familiar elevations; therefore, aerial photographs remain unintelligible to most people. You would be surprised by the number of people who cannot read blueprints because of their inability to fuse all sectional drawings into a dynamic tridimensional gestalt. Cubism is four-dimensional perspective; the art of Cubism makes no sense to people who cannot analyze plural perspectives and recombine them mentally to form a hyperspacial image of the pictorial subject.
Cognitive dissonance is produced by harmonic discord among the vibrations defining ideas, images, and sounds. All differences produce cognitive dissonance until discordant phases are cancelled and the remaining vibrations are resolved into a harmonically integrated gestalt in a higher dimension, like a musical chord. Wave cancellation is the physical basis of the concept of psychological repression established by Freud; these wave mechanics also produce karma.
Interference between (mental) waves transforms them into other frequencies so that objects are not perceived as they really are, if they are not rendered altogether invisible as a consequence of cognitive dissonance. Therefore, each person sees and hears truly only those signals that are congruent with the conceptual patterns already defining one's own mental structure; all other perceptions are distorted and repressed, occulted behind the Veils of Maja. At the bottom line, intereference produces a pair of predominant patterns separated by 180o of phase. As a result, reality is perceived to be polarized between good and evil, black and white, strong and weak, male and female, etc.
Just as only one side of a solid structure can be seen at a time, without a mirror, only one phase of a hyperspacial structure can be perceived directly at one time. It is natural, therefore, to assign a unique identity to different phases that exceed the observer's capacity for resolution into a single gestalt. Virtue is not recognized as the front of vice, no light is seen in darkness, and you have to know your tao to find strength in compliance. Union of complementary opposites transforms them both into a structure of higher dimension. The degree to which you can resolve polar opposites establishes the dimensional scope of your Consciousness. An understanding of hyperspace enables you to answer problems that defy all philosophers limited to three-dimensional concepts.
Assigning different identities to different aspects of the same structure is most commonly experienced in interpersonal relationships. During the initial rush of love, all perceptions that trouble the purity of the relationship is repressed. Admonitions from friends and family to watch where you are giving your heart are ignored as utterly irrelevant to the paragon identified with all the virtues of true love, and none of the vices. When dissonant aspects of the loved one appear from behind the Veils of Maja, they are perceived to belong to another person, a stranger in your home and a devil in your bed.
Unable to conceive that pleasure and pain can come from the same parent, infants perceive a good true-parent and a wicked step- parent. Most people still cannot identify God with the devil, nor can they perceive that Heaven and hell are complementary aspects of one real world.
Male and female mentalities are imprinted with different concepts making it physically impossible for the opposite sex to receive the same message that is sent. Communication between sexes is like communication between different species. No matter how many times arguments are settled, the very next argument is the very same argument. Acquiescence is not agreement, but resignation and tolerance of the incomprehensible.
If Freud studied physics before medicine, he wouldn't have invented a square wheel in his theory of sexual determinism. Psychology and psychiatry would be radically different if a grounding in elementary physics were prerequisite. These professions will soon be demolished and reconstructed by the hard science of Artificial Intelligence.
The soft sciences are not soft by their very nature, but because soft ideas attract people incapable of comprehending hard, mathematical concepts, and once soft-heads populate a profession, hard-heads move out of the neighborhood. As a consequence, the soft sciences degenerate into nonsense until they become too impractical to hold their customers. If astrology were not so soft-headed, actuaries would be calculating horoscopes instead of statistics.
The essential difference between the hard-head and the soft- head is concentration of mental focus. Whereas the hard-head defines particulars, the soft-head senses the overview. Both heads are half-wits if they cannot vary the scope of their focus to integrate particulars with wholes to comprehend both at once in a higher dimension of Consciousness.
Zen Masters are fond of answering disciples asking for wisdom by a question called a koan. Koans are believed to be nonsense intended to confuse one's mind until a critical tension precipitates a mystical insight. Koans are not nonsense; they are a special kind of question to which you already know the answer, but you don't want to know you know because such knowledge is self-knowledge; the most heinous crime of this civilization is to be caught in possession of self-knowledge. Self-knowledge, you see, is the special kind of knowledge that releases a person from the karmic wheel of life and the rule of Satan, however you conceive your devil.
Your mind is a house of many mansions. Most people never see the doors in the walls of their nurseries; they spend their entire spiritual lives confined in the crib where they were born, while they can only wonder about the sounds of family activity that transpire dimly into their windowless compartments. Once you realize that the barriers limiting your experience are merely partitions, you will open the doors of your mind to explore the manifold halls of self-knowledge. You may even leave your father's house to make your way as a grown person in the big hyperworld outside. Of course, it is dangerous out there, and not all who venture return sound and successful, but that is what real life is all about when play school is left behind.
You don't learn about hyperspace so much as you grow into understanding as a consequence of mental/physical/spiritual evolution, like you grow into walking, talking, and sexual consciousness. In short, hyperspace is not difficult to understand; if its meaning does not develop like music after some rumination, comprehension is simply impossible, so don't sweat it.
