The first four numbers symbolize the harmony of the spheres and the Cosmos as:
(1) Unity (Monad)
(2) Dyad – Power – Limit/Unlimited (peras/apeiron)
(3) Harmony (Triad)
(4) Kosmos (Tetrad).
The four rows add up to ten, which was unity of a higher order (The Dekad).
The Tetractys symbolizes the four elements—fire, air, water, and earth.
The Tetractys represented the organization of space:
the first row represented zero dimensions (a point)
the second row represented one dimension (a line of two points)
the third row represented two dimensions (a plane defined by a triangle of three points)
the fourth row represented three dimensions (a tetrahedron defined by four points)
