Cf. Sripatipaddhati, III-2, 5.
Slokas 10 ½-11½ : The Moon and Venus, when they are in an even sign or in a Navamsa owned by an even sign, get 1/4th of a Rupa as strength. It is reserve in the case of the other planets : i.e., the Sun, Mars, Jupiter, Saturn and Mercury get the same amount of strength (viz., 1/4th of a Rupa) when they are in an odd sign or in a Navamsa owned by an odd sign. When masculine, hermaphrodite and feminine planets occupy respectively the initial, middle or the last portion of a Rasi, 1/4th of a Rupa is to be assigned as their strength. The total of these 5 kinds of strength constituted the (Stthanabala) or Positional strength of planets, the first of the Shadbalas or six major divisions of strength.
(Vide Sripatipaddhati, III-4)
Sloka 11½ – 12½: Mercury and Jupiter are strong in the Lagna or East. The Moon and Venus are powerful in the 4th of North; Saturn in the 7th or West : Mars and the Sun, in the 10th or South. The strength of these planets is zero or nil when they respectively occupy the 7th place from the above. Such directional strength or (Digbala) in the interventing positions must be calculated by rule-of-three process.
Slokas 12½ – 14: In the bright half of a month, the (Pakshabala) of benefic planets corresponds to the number of Tithis passed in the Paksha, while that of the malefics, to the number of Tithis remaining to be passed or gone through. This process is reversed in the other or dark half of the month. The Pakshabala in the case of the Moon will be doubled. If a birth takes place in the middle portion of the Day, the strength (of the Rupa) accrues to the Sun ; if it be in the last or third portion of the Day, the strength goes to Saturn. The Moon gets it if the birth be in the first portion of the night. If the birth be in the middle portion of the night, the strength goes to Venus. If the birth takes place in the third or last portion of the night, Mars gets this strength. Mercury has it during the first portion of the Day. Jupiter has this strength at all times. This is called the (Ahoratraja) or (Dinaratritribhagabala). The (Nata) in ghatikas multiplied by 2 and divided by 60 will denote the (Natabala) in terms of a Rupa. (Cf. Sripatipaddhati III-9-14).
Sloka 14 ½: The same subtracted from unity will be the strength resulting from the (Unnata). The Moon, Mars and Saturn have the (Natabala), while the Sun, Mercury, Jupiter and Venus have the (Ummatabala). (Cf. Sripatipaddhati III-10).
Slokas 14 ½ – 15 ½: The ghatikas that intervene between mid-day and the Sun at a birth is termed (Nata), while (Unnata) indicates similar interval (in ghatikas) between the Sun and midnight. These two intervals when divided by 30 express the (Natonnatabala) of planets in terms of a Rupa, and form a sub-division of (Kalabala). About instruments (such as Sanku) and the like, they have been described in detail in the previous half of the work.
Cf. Sripatipaddhati I-3, III-10)
Slokas 15 ½ – 16 ½: The lord of the year, the lord of the month, the lord of the week-day and the lord of the (Hora=hour) have respectively ¼, ½, ¾, and 1 Rupa as strength when a birth has taken palce under their sway. The sum of these four kinds of strength goes to swell the (Kalabala). To find the lord of the Hora at any given time, multiply the ghatikas elapsed since Sunrise by 2 and divide the product by 5. The quotient will reveal the number of Horas that have elapsed. The lord of the first Hora on any week-day will be the lord of the week-day itself; the lords of the 2nd and succeeding Horas have to be reckoned from that planet in the following order: the Sun, Venus, Mercury, the Moon, Saturn, Jupiter and Mars.
Slokas 16 ½ – 17 ½: The Moon and Saturn are strong in their Southern course. Mercury possesses strength always. The rest become strong in their Northern course. The strength accruing from this is known as (Ayanabala). The planets taken in regular order from Mars should be declared to be strong when in their retrograde motion, their (Cheshtabala) being calculated from the degrees in there respective Sighra Kendras already described (by others). When two planets are conjoined in such a way that they happen to be in the same house and their longitudes agree even to the degree and minute, they are said to be in war and that planet which is North of the other is declared to be the conqueror and gains the strength of the other in the South who is considered as vanquished.
Slokas 17½ – 18½: Saturn casts a full glance over the 3rd and 10th houses, while the other planets view the two houses only with a quarter glance. Jupiter aspects the 5th and 9th houses with a full eye, while the rest see these houses with half a glance. Mars casts his full eye over the 4th and the 8th houses, while the other planets aspect them with 3/4ths aspects. All planets aspect the 7th with a full eye. Planets do not aspect the 2nd, the 11th, the 12th and the 6th houses reckoned from the one occupied by them.
Slokas 18½ – 19½: Subtract the aspecting planet from the aspected one. The result will indicate the extent in signs, degrees, etc., of the range of aspect. The (Drigbala) of the aspected planet (in terms of Rupas) can be accurately ascertained from these degrees, etc. by rule-of-three process by the addition to, or subtraction from, as the case may be, of the proportionate difference in strength between that fixed for that sign and the strength allotted for the succeeding sign. The Drigbala thus obtained should be classified under “Malefic” and “Benefic” according as the aspecting planets are malefic and benefic, and written in two tables in terms of Rupas. Their algebraic sum will reveal the exact Drigbala got for each planet. Cf. Sripatipaddhati-II.
SLokas 19½ -20½: The Sun, the Moon, Venus, Jupiter, Mercury, Mars and Saturn decrease successively by 1/7th of a Rupa in their natural strength. The (Nisargabala) of the Sun should be put down as one. The several kinds of strength, viz., those derived from (1) (Stthana-Position) (2) (Dik-Direction) (3) (Kala-Time) (4) (Nisarga-Natural) and (5) (Cheshta-motion) should now be totaled up.
