Berg on 13 Sign Zodiac

13-sign astrology

Further information: Ophiuchus (astrology)

Western tropical astrology has long been detached from the constellations eponymous of the signs, due to the axial precession of the equinoxes over the centuries since the introduction of the zodiac by the Chaldeans.

By contrast, in sidereal astrology the astrological signs remain attached to the constellations, while the vernal equinox has moved away from Aries over time.

Sidereal astrology has traditionally only been practised in Indian Jyotisha, but it has been introduced in western astrology by Cyril Fagan in 1944.

A small minority of western astrologers have since followed Fagan and used a sidereal system as in Indian tradition.

The Indian tradition also uses 12 equal-sized signs; the distinction is in where the signs start.

Berg breaks from historical tradition to combine sidereal astrology with the IAU's official constellation boundaries defined in 1930, creating a 13-sign system.

This results in astrological signs that correspond directly to the time the Sun spends in their eponymous constellations.

For example, the Sun spends forty-five days in Virgo and only six days in Scorpio.

The 13th sign is Ophiuchus, where the Sun passes during the first two weeks of December.

Berg argues that the movement of stars, planets, comets and asteroids through space affects the solar magnetic field; this in turn affects the geomagnetic field influencing collective and individual electro/chemical/biological systems.[citation ^needed] Human bio-resonant systems are able to tune into particular astro-resonant cycles. When constructing charts he uses dimension z in addition to the x and y coordinates which form the geometric patterns. The z co-ordinate is allocated an energy value of varying strength.[citation ^needed]
