The nature of the Sun's position
The calculation of the LagnaThe Ascendant; the point of the zodiac rising on the eastern horizon at a specific time. is determined from the wind-point. //20// Now, the Method for Calculating the Ascendant: One should know the day's position of the Sun, adjusted for the AyanamshaThe precession of the equinoxes; the difference between the tropical and sidereal zodiacs.. During the night, the calculation involves the rising times of the signs (Udaya) and the remaining portions of the Sun's movement in GhatisA traditional unit of time equal to 24 minutes.. //21// The elapsed time and the desired time in PalasA unit of time equal to 24 seconds; 60 palas make one ghati. should be subtracted in sequence. Then, the resulting figures should be multiplied by three. //22// When subtracted from the movement, this is clearly designated as the "Tenth" Referring to the 10th house or Midheaven calculation. //23// At the time of the Sun's movement, the calculation results in a clear value for the body (Tanu) The first house or the physical self through the rising times of the signs. //24//
Now, the Method for Calculating the Houses (Bhava):
The midday position, when adjusted by the elapsed time of the night, is combined. In the division of the quadrants, the "inclination" (Nata) and "un-inclination" (Unnata) are determined. //25// The calculation should be performed using the rising times at the equator (Lanka). By this method, the face of the calculation becomes clear. //26// The Ascendant and the Midheaven are refined; the difference is divided by three and distributed five times. Wise men should thus determine the SandhiThe "junction" or cusp between two astrological houses.. These six, when added to their opposites, complete the twelve houses. //27// 1/3 of the day and night If the movement is less than the Ayanamsha, it is the past portion of the house. This is seen in the nine junctions of the planetary movements. //28//
When the knowledge is equal, the fruit is full; in the middle, it is zero. Between the planet and the junction, the specific difference (Visheshaka) is found. //29// In the "descending" (Avarohi) state, the fruit is diminished at the junction of the primary planet. In the "ascending" (Aroha) state, the planet is strong; in the descending, it is middling. //30// Thus ends the Method for Calculating the Houses. The junction is the interval between planets in degrees and minutes. One should calculate the specific difference by the interval between the known position and the junction. //31// Thus ends the Specific Differences.
Now, the Ashtakavarga: A system of "Eight-fold Classification" used to determine the strength of planets based on their positions relative to other bodies.
From the Sun, the favorable positions are the 1st, 2nd, 4th, 7th, 8th, 9th, 10th, and 11th. From the Moon, it is auspicious in the 3rd, 6th, 10th, and 11th. From Mercury, it is auspicious in the 3rd, 5th, 6th, 9th, 10th, 11th, and 12th. //1// From Jupiter, it is auspicious in the 5th, 6th, 9th, and 11th. From the Ascendant, it is auspicious in the 3rd, 4th, 6th, 10th, 11th, and 12th. From Saturn, the Sun is auspicious in the 1st, 2nd, 4th, 7th, 8th, 9th, 10th, and 11th. //2// Thus ends the Ashtakavarga of the Sun.
From Mars, the 1st, 2nd, 4th, 8th, and 11th; from the Moon, the 3rd, 6th, and 11th; from Mercury, the 3rd, 5th, 6th, and 11th; and from Jupiter, the 1st, 4th, 7th, and 8th. //3// From Venus, the 6th, 7th, and 12th...
