It is not childish when you don't agree that the nonlinearity is important.

After all, you gave a linear formula and claimed that a linear formula is

sufficient. Because I think that the nonlinearity is important, I had to mention

it.

 

It seems useless to talk to you in words (you are only unfairly declaring me a

" liar " ). Let me change the language and talk in numbers.

 

Let us say we take someone born on Jan 1, 1909 and try to find his Tajaka annual

chart (based on true solar return) on Jan 1, 1918. Irrespective of the ayanamsa

one chooses, we know from modern astronomy that the change in ayanamsa between

these 2 dates is 8 arc-min 7 arc-sec, i.e. 0.135194 deg. Irrespective of the

zero-point we choose, change in precession between any given 2 dates is fixed

and we can accurately compute it. Using Shiv Hari's ayanamsa (24.45305 +

(Y-1990) x 0.013969712 as given here earlier), change in ayanamsa between

these 2 dates is 0.013969712 x 9 = 0.125727 deg. If the natal tropical position

of Sun is x deg, we are looking for Sun to reach the tropical position of

x+0.125727 when finding the true solar return with Shiv Hari's linear ayanamsa

(so that the sidereal position is the same). With nonlinearity taken into

account, this should be x+0.135194. Please note that this is independent of the

ayanamsa chosen and 0.135194 is the change in ayanamsa between these 2 dates for

*any* ayanamsa. This introduces an error of 0.009467 deg in the target tropical

position of Sun. Wrong target results in a wrong time. Multiplying by a factor

of 360, we get the resultant error in lagna a little above ****3.4

degrees****!!!

 

You may argue that true solar return should not be used etc. But the point is

that the above error of 3.4 degrees was introduced simply because a linear

formula was taken, though we know precession change is nonlinear. This error was

***avoidable***. Modern astronomy lets us compute the change in precession very

accurately (and the only unknown is the starting point). We don't know the exact

ayanamsa at the 2 dates, but we exactly know the change in ayanamsa between the

2 dates. But Sri Chandra Hari is introducing a considerable error in the

calculations because of the assumed linearity (an error of 3.4 degrees in lagna

is a lot and many divisional charts will change)! My only point is that this

error is ***avoidable***. Why not take the correct nonlinear formula as given by

modern astronomy? He says it is not important, but that depends on one's purpose

and attitude.

 

This is why I asked him why he took a linear formula and he gave an egoistic

reply and sidetracked the issue. " Who is lying " is an irrelevant topic on this

forum and I don't think the members are interested in such negative discussion.

Dear Sri Chandra Hari, I request you to concentrate on the technical aspects

instead. Please maintain decorum on this list. Please try to understand the

technical point raised.

 

We are all human beings and make mistakes - some small and some big. But the

negative approach of calling names and using words like " hypocracy " , " lying " and

" childish " achieves no useful purpose. With a positive approach, we can learn

from each other. Learning and sharing knowledge should be a process of universal

expansion and not a process aimed at personal glory and satisfaction of ego.

Atleast that is the spirit we try to maintain here. Kindly co-operate with us in

maintaining that spirit.

May Jupiter's light shine on us,
