“All this notwithstanding the exoteric element, as now found in the two Testaments, is quite sufficient to class the Bible among esoteric works, and to connect its secret system with Indian, Chaldean, and Egyptian symbolism.
The whole cycle of biblical glyphs and numbers as suggested by astronomical observations – astronomy and theology being closely connected – is found in Indian exoteric, as well as esoteric, systems.
These figures and their symbols, the signs of the zodiac, the planets, their aspects and nodes – the last term having now passed even into our modern botany to distinguish male and female plants (the unisexual, polygamous, monoecious, dioecious, etc., etc.) – are known in astronomy as sextiles, quartiles, and so on, and have been used for ages and aeons by the archaic nations, and in one sense have the same meaning as the Hebrew numerals.
The earliest form of elementary geometry must have certainly been suggested by the observation of the heavenly bodies and their groupings.
Hence the most archaic symbols in Eastern esotericism are a circle, a point, a triangle, a plane, a cube, a pentacle, and a hexagon, and plane figures with various sides and angles.
This shows the knowledge and use of geometrical symbology to be as old as the world.”
H. P. Blavatsky
