A line can be described as an ideal zero-width, infinitely long, perfectly straight curve (the term curve in mathematics includes "straight curves") containing an infinite number of points. In Euclidean geometry, exactly one line can be found that passes through any two points. The line provides the shortest connection between the points.

Line Stages of evolutionary development in cosmic manifestation are sometimes symbolized by the geometrical forms point, line, plane, solid, corresponding to unit or monad, duad, triad, and quaternary. Lines are therefore rays proceeding from an egoic center, and represent cosmic forces and, on the lower planes, the forces familiar in physics. These are dual, bipolar. In geometric symbols, lines may be combined, as for instance in the cross, where common agreement makes the vertical line masculine, the horizontal feminine; or in triangles, where the side lines and the base line each have its particular meaning. A line drawn in physical space may be regarded as a symbol for a real line, but to comprehend what the latter is, we must abstract the idea from all notions of physical space.
