Quotes:X

H. P. Blavatsky

X. X — This letter is one of the important symbols in the Occult philosophy. As a numeral X stands, in mathematics, for the unknown quantity; in occult numerals, for the perfect number 10; when placed horizontally, thus χ, it means 1,000; the same with a dash over it χ for 10,000; and by itself, in occult symbolism, it is Plato’s logos (man as a microcosm) decussated in space in the form of the letter X. The, or cross within the circle, has moreover a still clearer significance in Eastern occult philosophy: it IS MAN within his own spherical envelope.
