Narapatijayacarya 3.1.12

"Beginning with 'a'"—the meaning is clear.

Now, the day sound diagram:

a, i, u, e, o

1, 2, 3, 4, 5

6, 7, 8, 9, 10

11, 12, 13, 14, 15

5 5 5 5 5

20 27 27 27 27

Now, the ghaṭī sound diagram:

The ghaṭī sound is five ghaṭīs and twenty-seven palas; / its interval rising is stated to measure half a ghaṭikā.

"The ghaṭī sound"—the meaning is clear.

Now, he explains the interval rising of [the cycles] beginning with the twelve-year cycle:

Ending with the twelve-year cycle down to the day, from their own place and from their own time, / they rise again, and these sounds are elevenfold.

Year, month, day, nāḍī, and pala—in this order, / this measurement of time has been stated by me here in five ways in the svarodaya.

Whatever has elapsed of the twelve-year sound and the others, measured in palas, / divided by its own measure, produces the quotient, and the remainder becomes two [values].

In the quotient, the elapsed sounds should be known, and in the remainder, the rising sounds.

And when this is divided by sixty, the elapsed portion becomes the risen sounds.
