For many, including Pythagoras, Parmenides, Xenophanes, Plato, Aristotle and Plotinus, Monad was a symbol for God or the first being or the totality of all beings.
The Flower of Life (FOL) is a geometrical figure composed of multiple evenly-spaced, overlapping circles, that are arranged so that they form a flower-like pattern with a sixfold symmetry like a hexagon.
Leonardo da Vinci has studied the Flower of Life's form and its mathematical properties. He has drawn the Flower of Life itself, as well as components therein, such as the Seed of Life. He has drawn geometric figures representing shapes such as the platonic solids, a sphere, a torus, etc., and has also used the golden ratio of phi in his artwork; all of which may be derived from the Flower of Life design.
Monad being the source or the One meaning without division.
Monism is often erroneously seen in relation to pantheism, panentheism, and an immanent God. However, the concepts of absolutism, the monad, and the "Universal substrate" are closely related.
