Commentary on the Essence of Battle

For the five years beginning with Plavanga original: pallavaga; the 31st year of the cycle, the vowels starting with A [apply]. For the five years beginning with Paridhavi original: parigha; the 46th year, the vowels starting with A [apply].

For the five years beginning with Pingala the 51st year, the vowels starting with A [apply]. For the five years beginning with Dundubhi original: udumbya; the 56th year, the vowels starting with A [apply]. In this way, through these five vowels suvarna, the vowels starting with A act as the lords swami of the years.

In this system, regarding the motion of the time-segments kala-bhaga-antara-bhukti: what is the duration of a single segment? One segment is defined as the eleventh part. That itself is the "interval motion" antara bhukti or "interval rising" antarodaya. Within the twelve-year vowel cycle, the specific vowels must be determined by calculating this interval motion and interval rising.

He defines that very interval rising as follows:
In one year, [the sub-period is] one month (1), two days (2), forty-three ghatikas A unit of 24 minutes (43), and thirty-eight palas A unit of 24 seconds (38). Thus, repeating this 19 times using these measures of months, days, ghatikas, and palas, one finds the position of the interval rising.

Now, he declares the Season Vowel ritu svara:
Starting from the Spring season Vasanta, the "rising" of each vowel lasts for seventy-three original: saptatribhir, likely a scribal error for tri-saptati (73), as 73 days x 5 vowels = 365 days days.
