Guest guest Posted January 26, 2009 Report Share Posted January 26, 2009 Dear Mr. Patnaik , Ayanamsa is angular arc between two points namely initial point of sidereal Aries(Acvani) and first point of tropical Aries. First point of tropical Aries is called V.E.POINT .This is point of intersection of ecliptic and equator of date.Incidently both these planes are continuously vibrating due to gravitational and other forces exerted on earth mainly by Moon and Sun. Thus mean position of equinoxes go on varying slightly. This is corrected by addition or subtraction of Nutation of the day. Thus True position of equinox = Mean position of equinox - /+ value of nutation of the day Modern Astronomers calculate Nutation and Aberration based on new constants and there is a big advancement in this direction. This done based on1979 IAU THEORY OF NUTATION. (You may refer 'INDIAN ASTRONOMICAL EPHEMERIS' which is published every year by India Metrological Department). The second quetion arises as to how fix the initial point of sidereal Aries. This has to be fixed with help of some fixed star. The followers of Citrapakchha Ayanamsa recommend that Star Citra (Spica 16) should act as reference point and its sidereal TRUE longitude should be assumed as 180 deg on ecliptic. The following aspects are to be shorted out: 1. Every star has its proper motion. The longitude of Spica along the ecliptic has diminished by 60 sec during the period 1724 years from VE DAY falling in the year 285 A.D 2. The latest Sixth Fundamental Catalogue (FK6)indicates Mean tropical positions of the stars. On the other hand ,the apparent geocentric longitudes and latitudes are referred to the true equinox and ecliptic of date and corrected for planetary aberration. 3.Obuously , first point of Aries is to be fixed after taking into account the displacement in star position due to above factors. True position of star = Mean position of star -/+Nutation of the day =180 deg. Needless to say that modern astronomy has already measured these values , only astrologers are required to adopt them properly. Precession rate in long. per tropical year=50".29,per sid.year=50".26 Regards G.K.GOEL G.K.GOEL Get rid of Add-Ons in your email ID. Get yourname. Sign up now!

Alpha Arietis and Beta Arietis from the Vernal Equinox of date are about 38 and 34 degrees respectively As such, longitudes of either of the two stars should be the real Ayanamsha, as per your own definitions, which means the Ayanamsha as on date is either 38 or 34 degrees! To the best of my knowedge, however, no jyotishis is using that much of ayanamsha---all are circumnavigating betwen 22 and 25 degrees! Why? <The second quetion arises as to how fix the initial point of sidereal Aries. This has to be fixed with help of some fixed star. The followers of Citrapakchha Ayanamsa recommend that Star Citra (Spica 16) should act as reference point and its sidereal TRUE longitude should be assumed as 180 deg on ecliptic.> The Indian Astronomical Ephemeris takes the " intial point " as an imaginary point that was opposite to Star Chitra on the day of Vernal Equinox of March 285 AD! In fact, that is actually Lahiri Ayanamsha! Can you ever imagine something more incongruous and imaginary than a point which was opposite a particular star about two thousand years back? It is actullay Lahiri Ayanamsha on the shoulders of Chitra Star, when the poor Chitra has aboslutely nothing to do with it! Actually, late N. C. Lahiri was afraid of losing the sale of his Vishudha Sidhanta Panjika (Bangla) and Lahiri's Indian Ephemeris if he had switched over to Revati paksha, as had been advocated by B.G. Tilak, since that Ayanamsha (Revati) was less by about four degrees than that of Grahalaghava in 1940 or so. As the general public had become accustomed to Grahalaghava sankrantis then, they would not have tolerated a difference of about four days between Grahalghava Sankrantis and Revati Sankrantis! As such, Lahiri dovetailed his ayanamsha to Grahalaghava by taking shelter behind so called Chitra- paksha, which is as absurd as a human being can ever invent something! The same N. C. Lahiri inveigled himself into Saha Calendar Reform Committee in 1954 as its Secreatary and thrust down the throat of all the other members of that committee his own Ayanamsha by " geting it ratified " from hundreds of phalita jyotishis! Revati star, as the starting point of the zodiac, had a much better basis than that of Lahiri Ayanamsha, since Revati is at least a " Fixed Star " and not an imaginary point opposint a Star that is hudnreds of times larger than the sun! Revati Ayanamsha, as on date is around 20 degrees and not 24 (Lahiri) or 204 (actual Chitra longitude). It must be pointed out that if you select any point as the starting point of the zodiac, you have to take the mutual distances of planets etc. from that star on a day to day basis and not keep that " base " fixed permanently for an indefinite number of years as is being done in the case of " Chitra " (read Lahiri) Ayanamsha! I must also put on record that there is no sidereal or tropical zodiac! Zodiac is just one and it is the constellational belt as per IAU constellations! It cannot be divided into twelve neat and equal compartments which may have fancy names like Lahiri Mesha, Vrisha etc. or Ramana Mesha, Vrisha etc. or Chandra Hari Mesha, Vrisha etc. or Fagan Mesha, Vrisha etc. or of late Shakuntala Devi Mesha, Vrisha Rashis etc. and so on! We must not, of course, forget the so called Sayana Mesha, Vrisha divisions---the original Chaldean astrological signs, which Maya the mlechha thrust on Hindus via the Surya Sidhanta--too are imaginary. All the ayanamshas are thus baseless and meaningless, and that is why " Vedic astrologers " claim to be able to make correct predictions from all of them, since " Vedic astrologers " (including " Sayana Vedic " , of course!) can make correct predictions only from incorrect data! The only " blessings " of all these ayanamshas galore have been that we are celebrating all our festivals and muhurtas on wrong days! And that is why I keep on repeating, " We do not need enemies to ruin our dharma since 'Vedic astrologers' are doing that job in a much more 'satisfactory manner' than any enemy could have done it " . With regards, A K Kaul The actual Chitra Ayanamsha, as on date, should thus be 204 degrees, since that is the actual longitude of that star from the Vernal Equinox of today! But it is too much to expect any scientific basis from jyotishis!
