Pranam AYANAS
1 *Ayana* is known in *Jyotish Veda* as a period of time during a year when Surya <https://vedictime.com/en/library/graha/surya> (the *Sun*) moves to a certain direction passing certain Rashi <https://vedictime.com/en/library/rashi>. Ayana (अयन).—Northward or southward motion of a planet. Note: Ayana is a Sanskrit technical term used in ancient Indian sciences such as Astronomy, Mathematics and Geometry. 2 From the moment of touching the tropic1 of Makara <https://vedictime.com/en/library/rashi/makara> (*Capricorn*) (so-called tropical *Makara Sankranti*), Surya <https://vedictime.com/en/library/graha/surya> moves northward till it reaches the tropic of Karkata <https://vedictime.com/en/library/rashi/karkata> (*Cancer*). During its northward movement, which is also called as *Uttara Ayana*, Surya <https://vedictime.com/en/library/graha/surya> passes through the signs of: - Makara <https://vedictime.com/en/library/rashi/makara> (*Capricorn*), - Kumbha <https://vedictime.com/en/library/rashi/kumbha> (*Aquarius*), - Meena <https://vedictime.com/en/library/rashi/meena> (*Pisces*), - Mesha <https://vedictime.com/en/library/rashi/mesha> (*Aries*), - Vrshabha <https://vedictime.com/en/library/rashi/vrishabha> (*Taurus*) - and Mithuna <https://vedictime.com/en/library/rashi/mithuna> (*Gemini* ). This period in *Vedic *tradition is considered to be auspicious, as it's known as "*Deva Day*", and all events taking place at this time, are under supervision of Devas (Gods). So it is believed that this period is auspicious for holding such big events as marriage, moving into a new house and so on. 3 Similarly, from the moment of touching the tropic of Karkata <https://vedictime.com/en/library/rashi/karkata> (*Cancer*) (so-called tropical *Karkata Sankranti*), Surya <https://vedictime.com/en/library/graha/surya> (the *Sun*) begins its southward journey, known as *Dakshina Ayana*, till it reaches the tropic of Makara <https://vedictime.com/en/library/rashi/makara> (*Capricorn*). During its southward movement, Surya <https://vedictime.com/en/library/graha/surya> passes through the signs of - Karkata <https://vedictime.com/en/library/rashi/karkata> (*Cancer*), - Simha <https://vedictime.com/en/library/rashi/simha> (*Leo*), - Kanya <https://vedictime.com/en/library/rashi/kanya> (*Virgo*), - Tula <https://vedictime.com/en/library/rashi/tula> (*Libra*), - Vrshchika <https://vedictime.com/en/library/rashi/vrshchika> (*Scorpio* ) - and Dhanu <https://vedictime.com/en/library/rashi/dhanu> (*Sagittarius* ). This period in *Vedic *tradition is inauspicious, and is known as "a night of *Devas*" when all events taking place at this period of time are under the supervision of the *Asuras *(demons). 4 दैवे रात्र्यहनी वर्षं प्रविभागस्तयोः पुनः । अहस्तत्रोदगयनं रात्रिः स्याद् दक्षिणायनम् ॥ ६७ ॥ *daive rātryahanī varṣaṃ pravibhāgastayoḥ punaḥ* | *ahastatrodagayanaṃ rātriḥ syād dakṣiṇāyanam* || 67 || One ‘year’ (of men) forms the ‘Day and Night’ of the Gods; and the division of these is that the ‘Northern course’ is the ‘Day,’ and the ‘Southern Course’ the ‘Night.’—(67) Manusmrithi 39.1.67 5 आपो नारा इति प्रोक्ता आपो वै नरसूनवः । ता यदस्यायनं पूर्वं तेन नारायणः स्मृतः ॥ १० ॥ 6 1 10 Manu smrithi *āpo nārā iti proktā āpo vai narasūnavaḥ* | * tā yadasyāyanaṃ pūrvaṃ tena nārāyaṇaḥ smṛtaḥ* || 10 || Water is called ‘nara,’—water being the offspring of nara; since water was the first thing created by (or, the original residence of) that being, he is, on that account, described as ‘nārāyaṇa.’—(10) 6 AYANAMSA: It is used in the computations of the Jatagam and in many astrological factors; there are many ayanamsas ,mathematically establisged by the ancient civilisation, because of which, in “sandhi jatagas” planetary positions might change and predictions may differ; in the rest the predictions on account of the navamsas and shodamsa etc divisions variation , might alter, the period of results to be endured positively or negatively. 6A Western astrology mostly uses the tropical zodiac, in which 0° Aries is fixed at the vernal point. The vernal point is the point where the Sun is located at the spring equinox. By contrast, sidereal astrology uses a sidereal zodiac whose initial point is defined relative to the fixed stars. The concept originates from the Indian tradition, which has become known as "Vedic" astrology in recent years. Or "Indian astrology" is the “sidereal astrology". 6B *Precession *meaning in physics is the change in orientation of a rotating body with respect to its rotational axis. Precession in a sentence can be defined as the rotational movement in the rotational axis of a rotating object. The phenomena of precession are closely associated with the action of a gyroscope or a spinning top. It refers to the slow rotation of the axis of rotation of a rotating or spinning object about a line intersecting the spinning axis. The movement of astronomical bjects on their orbits and the slow and circular movement of a spinning top can be referred to as Precessional motion. 6C In physics, precession movement is basically of two types: torque-free and torque induced. In precession, torque-free signifies that no external force or torque is applied on the rotating object. In this kind of precession movement, the angular momentum is constant, but the angular velocity changes with time. The change in the body’s angular velocity in torque-free precession is brought about by the moment of inertia. : In physics, gyroscopic precession definition is the phenomenon in which the axis of a gyroscope or any other spinning object describes a cone in space when an external force is applied on induced into the object. The phenomena of torque induced precession can be observed primarily on spinning toy tops and gyroscope, and this is why it is amed gyroscopic precession. In a spinning top, the weight of the top acts downwards from its centre of mass when it is in a rotational motion. The normal force of the ground acting upon the top pushes it when it comes in contact. The weight and the force of the ground act on the spinning top to produce torque and bring about precession. Newtonian Precession According to classical Newtonian theory, precession can be defined as the change of angular velocity and angular momentum produced by torque. 6D The above is science as well as the ASTRONOMY DRAFTING THE Astrology. If anyone find it difficult to follow, simple explanation is that the revolutions of the planets is not regularly consistent with the same speed and arc of rotations; they change their gyrations due to weight or Mass. (F-ma is a variable factor due to the external factors in the space and in ayanamsa we are discussing about the earth ayanamsa in astrology. ) (similar variations do occur in the space with every planet and even stars ; astrologers name it as VAKRAM) In such situations, precessions cause wobbling and axis-revolving-around, to displace by few degrees, periodically. Since the vernal point makes a slow-motion relative to the fixed stars, namely the so-called precession of 1° in 71.6 years, the tropical and the sidereal zodiacs slowly drift apart. About 1500 - 2000 years ago, both zodiacs almost perfectly agreed with each other. However, in our time, the difference between them amounts to 20° and continues increasing. 6E That is periodically in millennium years poles reversal occurs. That is the south pole become the north pole and vice versa. Trisanku episode of Viswamitra is an allegory of the North pole Druvan reversing to south pole Trisanku, which when failed, stood as North pole as Druvan and the south pole as Trisanku which can be noticed in the space universe map even today. The movement of one degree every 71.6 years precession, calculated originally in the Vakya panchangam, was found to be erroneous and hence Dirk ganitha panchangam was evolved. And as and when many astrologers from Varaha Mihirar down J Krishnamurthy of Krishnamurthy paddati felt, as required corrections, many ayanasams have come into vogue. The variation of 20 degrees in the last 2000 years, will be adding up when the pole reversal would occur as the axis of rotation of the earth, would move in the opposite sides of rotations. 6F New ayanamshas are invented almost every year. Beginners in sidereal astrology are confronted with the difficult problem of deciding which ayanamsha to use, unless they choose to follow the recommendation of their teacher. Hindu astrologers and their western disciples mostly use the so-called Lahiri ayanamsha, whereas the western sidereal tradition mostly uses the Fagan/Bradley Ayanamsha. 6G How ever I use KP (Krishnamurthy Paddadi ayanamsa which corrected the drik) ayanamsa or lahiri which is used ny the north Indians also. If some one were to ask astrological predictions are farce as it did not happen so, -I would like to state that the computational jadagam and the Time of Birth checked by the deliverer by few seconds, added by the used ayanamsas and the intuitive analysis failure of the astrologer, could , waylay it as wrong; but not the science. Ayana is important in the calculation of the sun movement which in turn calculated the moon movement the rasiyadipathi. 6H THE NUMBER OF AYANAMSAS INCLUDES: Fagan/Bradley Ayanamsha, Lahiri Ayanamsha, True Chitra Paksha Ayanamsha, Suryasiddhanta Chitra Ayanamsha, Krishnamurti Ayanamsha, Ayanamshas Fixed at Revatī (zeta Piscium) or the Galactic Centre, * Suryasiddhanta Revati Ayanamsha, Usha & Shashi Ayanamsha, Dhruva Galactic Center Middle Mula Ayanamsha (Ernst Wilhelm), Sassanian Ayanamsha, Hipparchus Ayanamsha, Cochrane Ayanamsha:, B.V. Raman Ayanamsha, Shri Yukteshwar Ayanamsha, True Pushya Ayanamsha, Bhasin Ayanamsha, "Vedic Ayanamsha", Babylonian Ayanamsha (P. Huber), Vettius Valens Ayanamsha, Chandra Hari, "Ayanāṃśa", Skydram Ayanamsha (R. Mardyks), Ardra Galactic Plane Ayanamsha, Esoteric Ayanamshas, Aryabhata 522. 7 Movement of ayana every year twice thus is more important in the kala pramana . Next pole reversal could happen after 35 generations from now approximately.
