The dot is the most important of all figures, for every figure is an extension of the dot and the dot is the source of every figure. You cannot let a pen touch paper without making a dot first of all. It is simply the extension of the dot in two directions which is called a horizontal and a perpendicular line. And again, it is the dot which determines sides; if it were not for the dot the sides, as above, or below, or right, or left, could not be determined. The origin of all things and beings may be pictured as a dot. This dot is called in Sanskrit Bindu, the origin and source of the whole being. Since the dot is the source of the perpendicular and the horizontal lines it is the source of all figures and characters of all languages that exist and have existed, as doubtless it is the source of all forms of nature. The principal thing in man's figure is his eye, and in the eye the iris, and in the iris the pupil, which signifies the dot.
