I am beginning to believe that the western approach to astrology is more ego oriented and exemplifies the physical aspects of a persons aura, while the eastern approach to astrology goes beyond our small solar system, recognizing stars and their influences and shows the larger aspects of a person’s consciousness and spiritual goals.
The eastern approach shows the position of the stars accurately and the western approach uses all the present planets known to science and astronomy. Neptune having spiritual and psychic influences and Uranus bring awakening and discovery. Pluto’s job is to transform us.
I consider a sidereal chart somewhat more spiritual because it is more dependent on the correct location of the stars and not the ego orientation of western astrology based on the seasons and the Sun; which after all is symbolic of the ego. Without denying the tropical or western astrology we can combine the far off planets to the Vedic system to create and astrology for the Dwapara Yuga.
Sidereal and tropical are astrological terms used to describe two different definitions of a year. They are also used as terms for two systems of ecliptic coordinates used in astrology. Both divide the ecliptic into a number of "signs" named after constellations, but while the sidereal system defines the signs based on the fixed stars, the tropical system defines it based on the position of vernal equinox in the northern hemisphere (i.e., the intersection of the ecliptic with the celestial equator). Because of the precession of the equinoxes, the two systems do not remain fixed relative to each other but drift apart by about 1.4 arc degrees per century. The tropical system was adopted during the Hellenistic period and remains prevalent in Western astrology. A sidereal system is adopted in Hindu astrology, and in some 20th century systems of Western astrology.
While classical tropical astrology is based on the orientation of the Earth relative to the Sun and planets of the solar system, sidereal astrology deals with the position of the Earth relative to both of these as well as the stars of the celestial sphere. The actual positions of certain fixed stars as well as their constellations is an additional consideration in the horoscope.
