“The solution of the great problem of eternity belongs neither to religious superstition nor to gross materialism. The harmony and mathematical equiformity of the double evolution – spiritual and physical – are elucidated only in the universal numerals of Pythagoras, who built his system entirely upon the so-called “metrical speech” of the Hindu Vedas.
It is but lately that one of the most zealous Sanskrit scholars, Martin Haug, undertook the translation of the Aitareya Brahmana of the Rig-Veda. It had been till that time entirely unknown; These explanations indicate beyond dispute the identity of the Pythagorean and Brahmanical systems.
In both, the esoteric significance is derived from the number: in the former, from the mystic relation of every number to everything intelligible to the human mind; in the latter, from the number of syllables of which each verse in the Mantras consists.
Plato, the ardent disciple of Pythagoras, realized it so fully as to maintain that the Dodecahedron was the geometrical figure employed by the Demiurgus in constructing the universe. Some of these figures had a peculiarly solemn significance.
For instance four, of which the Dodecahedron is the trine, was held sacred by the Pythagoreans. It is the perfect square, and neither of the bounding lines exceeds the other in length, by a single point.
It is the emblem of moral justice and divine equity geometrically expressed.
All the powers and great symphonies of physical and spiritual nature lie inscribed within the perfect square; and the ineffable name of Him, which name otherwise, would remain unutterable, was replaced by this sacred number 4 the most binding and solemn oath with the ancient mystics – the Tetractys.”
