Ayanamsa matters A LOT in solar ingress charts!!

[Guest guest]

Dear Alfonso,

 

While catching up all my mail, I found your original article quoted by

Sanjay in a follow-up. I want to correct a wrong/misleading statement.

You've got to be careful here - lunar and solar charts behave totally

differently in ayanamsa error sensitivity. I will elaborate:

Nope, ayanamsa doesn't matter much in lunar charts, but it matters big in

solar charts.

 

On average, Sun moves by 1 arc-minute in one ghati (24 minutes). Let us say

my ayanamsa and your ayanamsa differ by a meagre 5 arc-minutes. Now this

means that solar ingress time will differ by 5 ghatis, i.e. 120

time-minutes. This is often enough to change the rising sign, because

ascendant changes sign once in every 2 hours on average.

 

In the case of solar charts, the error amplification ratio of (1) the

motion speed of lagna and (2) the motion speed of Sun, is so large that the

error in lagna is highly sensitive to the error in ayanamsa.

 

In the case of lunar charts, the error amplification ratio of (1) the

motion speed of lagna and (2) the motion speed of Sun-Moon differential, is

smaller and so the error in ayanamsa has a much smaller impact on the error

in lagna.

 

LESSON: When casting lunar new month charts (Sun-Moon conjunction charts),

you need not split hairs about ayanamsa. But when casting solar new

month/year charts (e.g. Capricorn ingress), you need to have an exact

ayanamsa. Even a few minutes error in ayanamsa makes a big difference.

 

May Jupiter's light shine on us,

Narasimha
