This is a basic explanation of the difference between Vedic Sidereal Astrology and Tropical Western Astrology
Tropical Astrology follows as though the earth is sitting in an upright position.
Imagine the Earth's axis being vertically straight.
Although the Earth, is not sitting in an upright position.
It’s axis is positioned at a 23.5 degree angle.
This 23.5 Degree positioning is only recognized in Vedic Sidereal Astrological Teachings
The picture below shows the actual axis of the earth (Solid Yellow Line):
Therefore: Tropical Astrology does not take into account a huge 23.5 degree difference in astrological science. This 23.5 degrees makes a significant difference to any Natal Birth Chart. Leading you to believe many things about yourself, that may not be necessarily true.
