The Essence of Tajika Astrology (1820) - Page 11

The own-sides referring to mathematical constants or "polarities" are 20. In Libra, the first parts are 4, the arrows are 55, and the earth-moons are 11. In Scorpio, the flavors are 6, the elephant-actions are 48, and the sky-sides are 20. [Verse 15] In Sagittarius, the earth is 1, the seven-earths are 17, and the two-moons are 12. In Capricorn, the hands are 2, the logic-qualities are 36, and the three-Vedas are 43. In Aquarius, the ages are 4, the Rama-deities are 3, and the three-twins are 23. In Pisces, the arrows are 5, the eye-arrows are 52, and the sky-sides are 20. [Verse 16]

Now, he describes the additive factors for the Sun's transit Sankranti: the moment the sun enters a new zodiac sign through the meter of the verse: "The flavors are these eyes," "In Leo, the flavors," and "In Sagittarius, the earth"—these are easily written into the instrument likely referring to a physical astronomical table or astrolabe.

Now, the Calculation of the Lunar Day (Tithi)

The Shaka era year the traditional Indian calendar system minus 1445, divided by eleven 11, then increased by the result of 170, then added to eleven 11, and divided by thirty 30, gives the remainder. The additive factors are: sky-moon-fire-arrows 310, seven 7, and the own-variables. When the remainder is added to these ten values in order, and placed in twelve positions, these are the approximate Lunar Days Tithis: a lunar day, 1/30th of a lunar month arising from the Sun's transit. [Verse 17]

Now he explains the calculation of the transit's lunar day: "The Shaka era is the arrow..."—by using one's own lunar day additives, the remainder is placed in twelve positions and added; thus the approximate lunar days of the transits are found. By using the term "approximate," the forest-regulator likely a reference to a specific astronomical authority or rule indicates that in the previously obtained weekday...
