I recall the first time I tried to have my horoscope done in in Hyderabad that the astrologer could not properly calculate it especially my lagna, because he had never done the chart of someone who was not born in India. The script is Kannada. One of my main astrology teachers, Sriman B.
Sashikanta Jain of Bangalore, with whom I studied from was a specialist in prasna sastra. This meant that the lagna to be calculated was always for the same city, Bangalore.
And since the client was sitting in front of him expecting an answer it had to be done quickly. Since all his clients came to him in Bangalore he only had to calculate the lagna for one place. What he did was to get a very large book and for every day of the year he made a table for what times the lagna would change on that day. Not only the lagna but also the change of navamsas within that lagna were tabulated. Since the Vedic day begins at sunrise and the sidereal position of the sun would be known for that day every year it was easy to calculate what the times for each lagna and navamsa would be using the rules in karana and sarini texts.
Even today his son uses this old hand written book as a backup for calculating the lagna if his computer is not available. The point being that the author Laura Barat has no experience of the ground realities and how traditional Vedic astrologers used the principles found in the Surya-siddhanta on a day to day basis. And from this lack of understanding of the text and cultural matrix it comes from she and those she is echoing have come up with all kinds of inaccurate notions. Living in obscure parts of the universe 10, miles from India and without any gurujana to guide them leads to such conclusions.
This shows why one needs to have a guru so that one does not go on wild goose chases. As in all aspects of Vedic culture what is written is only a small portion of the teachings the rest comes from the oral tradition of the Guru-Sishya interaction. Tradition is also a very important pramana Srimad Bhagavatam As Srila Prabhupada would explain that one cannot become a doctor just by reading some medical books. The tradition of using sidereal system going from Guru to Sishya is very clear.
This is also the tradition of my param guru Srila Bhaktisiddhanta Sarasvati Thakura who was a Jyotish Acarya; he first published his translation and commentary on the Surya-siddhanta at the age of 16! He also wrote a translation and commentary on Siddhanta Siromani and several other texts.
To understand just how impractical and ludicrous the idea of using the Surya-siddhanta for calculating horoscopes is let us take a modern example from the West. Robin M. This page text contains all the formulas used by astronomers, as the blurb from the back cover says:. This is an introductory textbook on spherical and positional astronomy.gelatocottage.sg/includes/2020-11-18/595.php
Surya Siddhanta - WikiVisually
It is entirely suitable for use by students with no prior knowledge of classical astronomy. At the same time, it is sufficiently comprehensive to make it a useful background reference book for anyone engaged in practical astronomy. The first three chapters sketch essential background: mathematical techniques and coordinate systems. Successive chapters then give treatments of refraction, aberration, stellar parallex, precession, nutation and proper motion. An entire chapter is devoted to astrographic plate measurements. The gravitational two-body problem is solved and applied to solar system dynamics.

Novel areas include a full treatment of binary star orbits and two chapters on developments in radio astronomy. Worked examples and problems to be solved by the reader ensure that this is a valuable textbook. This text gives all the formulas, and much more, that an astrologer would need to calculate a horoscope. But no astrologer would ever use this text to calculate anything.
Instead what they would do is use an ephemeris like The American Ephemeris at Noon that is calculated using the principles found in Mr. For those of you who have never calculated a chart by hand an ephemeris is a catalog of the daily motion of the planets in case of the Moon usually every 12 hours in relation to a certain time and place.
Knowing the planetary position at a specific time and place the astrologer can interpolate what the planetary position will be for the time and place where the chart needs to be calculated. With a little practice you can erect the basic horoscope in minutes depending on your mathematical abilities. Try doing that with a text on spherical astronomy! They instead create a digital ephemeris such as the JPL or Swiss ephemeris and using that ephemeris the software interpolates the planetary position and creates the chart.
Because it takes a lot less number crunching to interpolate between already calculated planetary positions than to calculate the planetary position from basics using astronomical formulae. Using a digital ephemeris such transit searches take mere seconds to calculate but would take significantly longer using the brute force method. On this link is a PDF example of a transit search from of the major planets Mars, Jupiter, Saturn and Rahu to all the other planets and also includes sign ingresses.
But this example shows why even modern computer software uses digital ephemerides rather than doing brute force calculations, it just makes more sense. Reverting to our original topic, for exactly the same reason no one would use the Surya-siddhanta to calculate a horoscope any more than they would use Mr. Instead the practitioner would use an ephemeris calculated on the basis of these texts.
The Precession and the History of Mankind
In jyotish such ephemeris texts are called sarini. From their website:. But rather uses a digital ephemeris. And using an ephemeris is what all astrologers have done all over the world since the beginning. So it is absurd to postulate that anyone in Vedic culture would calculate a horoscope using anything other than a sarini text. And, it is even more absurd to create a whole system of astrology based on that. Tajika techniques, which originated in Tajikstan, an ancient Persian culture, are the originators of Greco-Roman astrology and thus, modern day Western Astrology.
Rather so-called Persian astrology lying between India and the Mediterranean is an amalgam of Hellenistic and Vedic astrology. Early Hellenistic writers like Dorotheus of Sidon were translated into Persian. And regarding Tajika, those who do use Tajika in India use a sidereal zodiac not tropical.
Modalities of the Rasis Signs Another valid argument for using the Tropical Zodiac and confirming the relationship of Rasis to the intertwined movement of the Sun and the Earth is the modalities of the Signs. Aries, Cancer, Libra and Capricorn are called moveable signs. Their common characteristic is change and their beginning heralds a change in the Sun's movement. At 0 degrees Aries the Sun crosses the equator on its way North, changing from the Southern hemisphere to the Northern hemisphere. At 0 degrees Cancer the Sun changes from moving North to moving South. At 0 degrees Libra the Sun crosses the equator on its way South, changing hemispheres and at 0 degrees Capricorn the Sun begins to move North.
If the Rasis were sidereal and not based upon the Sun's movement in relation to the Earth, there is no valid reason why these particular signs would herald change. The dual Rasis, Gemini, Virgo, Sagittarius and Pisces, represent the Sun losing momentum on its course and getting ready for a new beginning. This is why these signs are energy transformers. The dual signs are steadfast and resolute just enough to get the job done but are also flexible enough to allow for necessary change.
Again, there is no reason for the aforementioned Signs to carry any of these qualities divorced from the fact of the Earth's relationship to the Sun. Just having a certain constellation of Stars behind the Sun does not automatically bring these characteristics, especially if such "constellations" do not carry consciousness as they do not per Parasara.
It appears to be because as an apostle of the tropical system she has not quite understood what the main proponents of the tropical system are saying. Here is a clearer statement by a famous tropical astrologer Steven Forrest. After describing how the motion of the Sun affects the seasons, he writes emphasis mine :. Astrology really has nothing to do with the stars themselves.

It is based solely on these variations in light, or, more simply, on the seasons. But what about Aries and Taurus and Capricorn? Those are constellations. They are stars. If they really have nothing to do with astrology why do we talk about them? Millennia ago, astronomer-priests noticed that on the morning of the day when light at last began to make inroads into the darkness, the sun rose into the stars of Capricorn. The constellation served as a convenient visual marker for the location of the sun along the ecliptic [the path of the sun through the zodiac].
Such knowledge helped our forebears in practical ways, such as timing the planting season. The convenience turned out to be temporary.

Traditions die slowly, though. The priests were accustomed to saying that when earth entered winter, the sun entered Capricorn. This slip-up produced no serious problems for astrology itself, but it has been hard on public relations. To the astrologer, Aries means something entirely different. Seasonal changes , then, not stars, are at the heart of sign symbolism. Through variations in the length of night, we mark four critical points that help us divide the circle.
