            The seven Rishis  [the seven dotes in the seal above] is the name of a
constellation the Big Dipper  [Saptarishi] in the past this constellation lined up with the
summer and winter as the 6th hour and 18th hour. The north pole moves 1 degree every
70 years in a circle called the precession of the equinox. The first star of the Saptarishi
that came the closes to the North Pole and lined up with the direction of the summer
solstice was Alkaid the last handle star 6480 years ago than the last star to line up with
the summer Solstice was Dubhe 3240 years from Polaris or 1228 BCE [Note 3240 x 2
= 6480].  When at Dubhe the North Pole was 15 degrees above the star. This changing
line through the solstices changes with respect to a conceptual fixed line starting from the
star Agasta in the south running through Polaris “Dhruva� and then the permanent
celestial pole and finally through Vega “Abhijitâ€�.  This difference was measured in
Yogas 60 degrees = 4320 years. A line formed through the Solstices and the other from
Agasta too Polaris then Vega form two lines that intercept at the celestial pole.
            The Siddhaantas (Aryabhatiya, Suryasiddhanta, Narada Purana) used a given
number of planetary revolutions.  A Mahayuga or yuga equals 4320.000 revolutions, the
moon 57753336, Jupiter 364220.  The Ardharatrikapaksa has the same numbers for
yoga the moon and Jupiter; it gives Saturn 146564, mars 2296824, Venus 7022388
and Mercury 17937020. Due to the precession of the equinox the shift through 1 degree
arc was 72 orbits today it is 71.6.   The time period for the equinoctial shift to go
through an astrological house (30 degrees) was 72 x 30 = 2160 than two houses were
2160 x 2 = 4320. The ancients multiplied the number by a factor of 1000 at the end of a
calculation they would have had to divide by 1000, today this is called in science the
precision of three decimal places.     

        The planet Jupiter above was given 364220 orbits , three decimal place precision
4320.000 / 364.220 = 11.86096 here 4320 / 364.2 = 11.86161 the precise
measurement of today of one orbit of Jupiter is 11.86 earth orbits  (earth orbit equals
4320/X as a ratio).
Saturn takes 10,759 Earth days or 29.5 earth orbits. The Vedic number of 146.564 /
4320 = 29.475.

                 The Siddhaantas ( Aryabhatiya , Suryasiddhanta , Narada Purana)  gave the
moon 57753336 and a Yuga  4320000 Three dicmal place precession   57753.336 /
4320 = 13.3688 x  27.32167 days per lunar orbit = 365.2587 the Julian calendar is
365.25 days of 86400 SI seconds The Earth’s rotation is slowing at a rate of 0.002
seconds per day per century.  As a result of the slowing there is a Conservation of
angular momentum the slowing of earth’s rotation is accompanied by an increase of
the mean Earth-Moon distance of about 3.8 m per century , or 3.8 m cm per orbit.

     Mars in science orbits the sun in 687 earth days.  The Vedic number 2296824 for
mars in the equation 4320 / 2296.824 = 1.88  then 1.88 x 365.25636 = 686.9953 The
Martian orbit is equal to 1.8809 Earth orbits,  , 320 days , and 18.2 hours , the Vedic
numbers 4320 / 2296.824 = 1.88085.

     Venus in science completes an orbit of the sun in 224.65 days.  The Vedic numbers
7022388 three decimal places 7022.388 / 4320 = 1.6255527 then 365.25636 a orbit
divided by the modern number 224.65 = 1.622589.

   Mercury in science takes 88 days to complete an orbit around the sun. the Vedic
numbers 17937020 , then 17937.02 / 4320 = 4.152 and 365.25636 / 88 = 4.15064.
We are looking backwards at their calendar for their calendar start with an Epoc as 3

          Since Agasta or Canopus is so far south in the sky, it never rises in mid- or far-
northern latitudes; in theory the northern limit of visibility is latitude 37°18; north. The
procession of the equinox is 25920 or 4320 x 6 years and a quarter of the procession is
6480 years making the North Pole more than 23 degrees further north than today. In
4467 BCE (6480-2013) Canopus could only be seen at 12 degrees latitude that is
about 25 degrees, 37 – 25 = 12 degrees. Today the continent of India starts at 8
degrees, 6480 divided by 25 is 259.2 years per degree (this is an estimation because a
quarter of the precession is more the 23 degrees approximately 25-27 degrees more)
4467 – 3100 = 1367 and 1367 divided by 259.2 = 5.2739 degrees then 12 +
5.2739 = 17.2739 degrees this is in agreement with the latitude of the Vindhya
mountains.
        
When you use the star Vega {Abhijit} as a reference star just as I used a quarter of the
procession, Vega was the pole star at half of the procession from today. That is 25920
years divided by two or 12960 years ago. Again "Since Canopus is so far south in the
sky, it never rises in mid- or far-northern latitudes; in theory the northern limit of visibility
is latitude 37°18; north" and today Vega is 18h 36m56.3364s, +38° 47′ 01.291â
€³.  Vega is at +38 latitude and the visibility of Canopus today with the North Pole 1
degree east of Polaris Dhruva is +37. This Calendar would use 46 degrees and not 23
as I used above, that is a quarter of the procession and the north pole is 23 degrees
north of Polaris and 23 degrees west of the Celestial pole, that is why I used 25 above
instead of 23, if you take a line from Canopus to 23 degrees past our North pole or the
celestial pole and make Canopus the center of a circle, that circle would miss the pole
that is 23 degrees at a right angle at the celestial pole [6480 years ago]. Today Canopus
is at 06h 23m 57.1099s, −52° 41′ 44.378″ and Vega is 18h 36m 56.3364s,
+38° 47′ 01.291″ so 6th hour is a straight line through the 18th hour and it
intersects  Abhijit , Agastya and between them dhruva (Polaris).   
dhruva mf(%{A4})n. (prob. fr. %{dhR} , but cf. %{dhru} and %{dhruv}) fixed , firm ,
immovable , unchangeable , constant , lasting , permanent , eternal RV.; the
unchangeable longitude of fixed stars , a constant arc ib.
The unchangeable longitude of fixed stars
Longitude (/ˈlÉ’ndʒɨtjuË�d/ or /ˈlÉ’ndʒɨtuË�d/, British also /ˈlÉ’Å
‹É¡É¨tjuË�d/),[1] is a geographic coordinate that specifies the east-west position of a
point on the Earth's surface. It is an angular measurement, usually expressed in degrees
and denoted by the Greek letter lambda (λ). Points with the same longitude lie in lines
running from the North Pole to the South Pole. By convention, one of these, the Prime
Meridian, which passes through the Royal Observatory, Greenwich, England, was
intended to establish the position of zero degrees longitude.
46 degrees above Dhruva would be the calculation of Vega, the actual is 5 degrees
more as Vega was 5 degrees south from the north pole 12960 years ago. 12960 /46 =
281.739 this is in conflict with 6480 divided by 25 is 259.2 years per degrees. Here 46
+ 5 =51 12960/51=254.1176.
In Hindu mythology, Vega is called Abhijit.   The author of Mahabharat, Maharshi Vyas,
mentions in the chapter Vana Parva (Chap. 230, Verses 8–11): "Contesting against
Abhijit (Vega), the constellation Krittika (Pleiades and 46dgrees) to "Vana" the Summer
Solstice to heat the summer. Then the star Abhijit slipped down in the sky." P. V.
Vartak suggests in his book, The Scholarly Dating of Mahabharat, that the "slipping of
Abhijit" and ascension of Krittika (Pleiades) might refer to the gradual drop of Vega as a
pole star since 12,000 BC. Vega is expected to become Earths Pole star by year
26,000 by some estimates.

Ketu is the dragon’s tail or descending node (considered in astron. as the 9th planet,
and in mythol. as the body of the demon Sain6hikeya [son of Sin6hika1] which was
severed from the head or Ra1hu by Vishn2u at the churning of the ocean, but was
rendered immortal by having tasted the Amr2ita) Hariv. 4259 R. VP. ; `" a pigmy raceâ

The descending node by today’s definition is at equatorial line or equinox the
descending node in the Veda is when the sun stops rising at the summer Solstice where it
begins its descent and Vishnu who represents the Sun Sleeps for four months and there
is the actual node. azleSAbhava or m. the Ketu (or descending node)

hour perfectly matching the timing of the seal.

 The seal conveys a date but the date in some way determines the written form of a
name or family.  When I realized this is happening I was confounded when you think of
the endless genealogies of the past.  The name here begins with Ketu [ke and the circle t
