The Astronomical Foundations of Astrology

The Ascendant is outlined as the intersecting stage between the Ecliptic and the Celestial Horizon and is the Jap Celestial Horizon. It is represented by the components

Tan L = Sin E / cos E cos w – Sin w Tan A

where A is Latitude of the area, w is the maximum declination of the Solar, E is the Ideal Ascension of East Level ( Sayana Kala Lagna ) & L – the Lagna.

Raseenam Udayo Lagnam – Udaya Lagna, the Ascendant, the pivot of the horoscope, is the Japanese Celestial Horizon. In Astrology everything is centered on Lagna, Sarvam Lagnepi Chinthayel.
