course of 200 years. But as per the Bīja-correction it
should be 52'. Hence it is a fact that there is a positive
error but not so much as indicated. But it must be noted
that Mercury's orbit has the highest eccentricity of as
much as .2, and the observer who stipulated the correction
must have observed when Mercury was near its perihelion,
where the error could have been as much as indicated and
even more. Similarly on close analysis it could be proved
that the Bīja-correction should have been as indicated,
say, roughly about 3600 Kali era, which might be roughly
the date of its stipulation.
Verses 9, 10. Concluding verses of the Madhyādhikāra.
If the work is made more voluminous by describing
various methods which are easy and interesting to un-
intelligent people, learned men look down upon such a work
as indulging in unnecessary verbosity. Hence the volume
of a work does not add to its greatness; So I have made my
work neither voluminous nor brief-worded. The reason is
that both the intelligent as well as the unintelligent people
are to be enlightened.
For the sake of clarity of exposition, different ingeni-
ous methods being used in such a way that the work does
not exceed the normal limits of the previous works, and in
corporating as far as possible unit numerators, fractions
having numerators and denominators mutually prime, using
methods of interpolation and reduction, making use of
different kinds of denominators and numerators in many
ways, this kind of treatment must be given to a work of
this nature by an intelligent man.
Comm. Easy.
Before we proceed to the next chapter, we shall add
here tables of astronomical constants as given by different
authorities, which will help comparison and appreciation of
the work.
