Hence, if higher space exists and our world borders upon it and lies partially in it, it follows necessarily that we see only portions of all objects. We never see their true and complete shape. We see their three measurements, but not their fourth. The new direction is concealed from us, and when I hold this book and move my hand all round it I have not really made a complete circuit. We only perceive those portions of any object which exist in our three dimensions, the rest escapes us. But, once learn to see in higher space, and objects will appear as they actually are. Only they will be hardly recognizable!
