The Great Compilation

Four zeros, five, the Vedas original: "Veda" representing the number 4, the flavors original: "Rasa" representing 6, fire original: "Agni" representing 3, the twins original: "Yama" representing 2, the fortnights original: "Paksha" representing 2, eight, the arrows original: "Shara" representing 5, and the moon original: "Indu" representing 1—these are the revolutions of the stars in a Kalpa Kalpa: An aeon in Hindu cosmology, equal to 4.32 billion years.
The Sanskrit verse uses word-numerals to express the number 1,582,236,450,000.

The planetary calculations established by Brahma have become obsolete due to their antiquity; for this reason, Brahmagupta, the son of Jishnu, writes a clear correction original: "sphuta" of them. He describes the flaws in the Epoch-divisions original: "Yugadi-bheda" cited by those ignorant people who speak in contradiction to the Brahma-Siddhanta. In one Kalpa, there are 1,582,236,450,000 sidereal risings.

Bhaskaracharya, who held Brahmagupta in the highest regard, also illuminated the year-measurements and stellar positions determined by Brahmagupta in his own work, the Shiromani.

The author of the Surya Siddhanta and other prominent astronomers have proposed the theory of the oscillating motion of the equinoxes Ayana: The precession of the equinoxes. However, to refute this view, Bhaskara wrote in his Vasana-Bhashya commentary: "If this was not observed, why was it stated by the authors of the Surya Siddhanta as authoritative tradition, like the circumference of the planetary orbits?" That is to say, if the era of the Surya Siddhanta and others was entirely within the precessional shift, why did they not reveal the theory of the stellar circle's revolution according to the views of Nara (the Vasistha Siddhanta)? However, Bhaskaracharya expressed this view without truly knowing the reason, which shall be written later. It is stated in the Surya Siddhanta:

In one Great Age original: "Mahayuga", the stellar circle advances eastward 600 (30 $\times$ 20) times. By multiplying the desired days original: "Ahargana" or years by 600 and dividing by the terrestrial days or years of the Age, one takes the result's arc original: "Bhuja", multiplies it by three, and divides by ten to obtain the Precessional Degrees original: "Ayanansha". Both the writing and the meaning of this verse are extremely complex. The core issue is: why put so much effort into explaining something that should be simple? This method is not desirable in mathematics. The alternative meaning understood by Bhaskaracharya will be written later.

The final quarter of another primary verse defining the precession has also become complex in meaning. For example:

Here, if the word "Dyuguna" is not interpreted as the "Total Days" original: "Ahargana", it cannot be reconciled with the previous verse in any way. Mr. Davis original: "डेंमिस" (likely a misspelling of Samuel Davis) also did not interpret this verse correctly. He wrote: "Multiply Ahargan (Number of mean solar days for which calculation is made) by 600 and divide the product by solar days in a yug, of quotient take sine and multiply 3 and divide by 10 to get ayanansha." The original text contains several printer's errors in the English quote, such as "qays" for "days" and "prodnct" for "product".

Whatever the case may be, it is understood from the first verse that according to the Surya Siddhanta, the annual motion of the precession is 54 seconds original: "Vikala".

Parashara’s view is that in one Kalpa, the stellar circle moves 581,709 times...
