Hayanaratna 7.17

Here is an example. At the year's entry Mercury has the fewest degrees, so it is written first. Then the lagna (rising sign), with a little more. Then the Sun, with more degrees. All are set out this way. Then take the smaller, Mercury, 0 signs 2 degrees 18 minutes 34 seconds. Take it from the larger, the lagna, 8 degrees 53 minutes 2 seconds. The rest, 0 signs 6 degrees 34 minutes 28 seconds, is written below the lagna. In this way the patyamshas (degrees left after subtracting) of all are found. Their total is 28 degrees 16 minutes 31 seconds. No least degrees are equal, so it equals the largest, the Moon's 28 degrees 16 minutes 31 seconds. Multiplied twice by 60 it is 101791. The solar year, 360, multiplied twice by 60, is 1296000. Divide 1296000 by 101791. This gives the dhruvanka (fixed multiplier): 12 days 43 ghatikas (24-minute unit) 55 palas (24-second unit). The planets' patyamshas are multiplied by it, by gomutrika (cross-wise multiplication). What comes from dividing by 60 is carried upward. These give the planets' dasha (planet period) lengths in days and so on.

Simple meaning: Worked example: the remainders add up to 28 degrees 16 minutes 31 seconds. Dividing 360 days by it gives a multiplier of about 12.73 days.
