Virgo

Thus, under the guidance of the spiritual hierarchies, focused through
the signs of CAPRICORN, SAGITTARIUS, SCORPIO, and LIBRA, were his physical,
moral and mental attributes acquired, and he was equipped and mental attributes acquired, and he was equipped to commence the spiritual side of his evolution. The germ of this progress is hidden in the celestial virgin, the sign VIRGO, which is the vehicle of the immaculate conception, the heavenly mother of Christ; not of one Christ only, but of many. This is one of the most sublime signs of the Zodiac and one of the most mystical, so fraught with hidden meaning that its full import cannot be fully understood save when viewed by the internal light of spiritual illumination. Yearly, at the winter solstice, the immaculate Madonna is ascendant at midnight, when the new born Sun commences to rise to the task of growing the grain and grape, to save humanity from the cold and famine, which would inevitably result were he to remain in the southern declination. The Sun is therefore an apt symbol of the Savior, born to feed his flock on the spiritual bread of life.
But, as we must have eyes attuned to light to see the sun, so must the
Christ be born within before we can perceive spiritual light. As Angelus
Silesius says:

"Though Christ a thousand times in Bethlehem be born
And not within thyself, thy soul will be forlorn.
The Cross of Golgotha thou lookest to in vain
Unless within thyself it be set up again."

Therefore, by the precessional passage of the Sun through the sign Virgo,
the germinal impulse was given towards the birth of Christ within man. The MYSTIC MARRIAGE of the lower self to the higher, the IMMACULATE CONCEPTION,
and the DIVINE MOTHERHOOD, which nourishes deep in its bosom, unseen by a
scoffing world, "THE NEW BORN CHRIST," are actual experiences of a growing
number of people. And without the celestial prototype, fructified by the
solar precession, this would be an impossibility; neither has this ideal
been realized in such fullness during the past ages as today. The reason of
this will appear when we take up the joint consideration of opposite signs
of the Zodiac.
