In the Mighty Circle of Light, the Kala Chakra   /    The distance traversed is Bhuja called / Koti is the untraversed degree ! / Oja Pada means the Odd Quadrant / In the next Yugma Pada. 90 to 180 / The traversed Degree is Koti / And Bhuja, the untraversed !  / This is the Equation of Bhuja !

                          

                         

           

                         

                         

                           

In the Great Circle of Light which is 360 degrees, ( the Bha Chakra, the Kala Chakra, the Zodiac ), the first 90 degrees are Oja Pada ( Odd Tri Signs ) and the next 90 degrees are Yugma Pada ( Even Tri Signs ). 

The Equation of Bhuja 

The degrees traversed by a planet is called Bhuja and the degrees yet to be traversed by a planet is called Koti in an Oja Pada. In a Yugma Pada, the degrees traversed by the planet is called Koti and the degrees yet to be traversed by a planet  is called Bhuja. In other words, the degrees traversed by a planet is the same in the first 0 – 90 degrees and in the second Pada, it is 180 – degrees traversed.  In the 180-270 degrees arc, it is distance traversed – 180 degrees and in the 270-360 degrees arc, it is 360 – distance traversed. This is known in Vedic Astronomy as the equation of Bhuja or Sine.  Bhujajya is radius multiplied by modern Sine.
