84. Jupiter, Mars, the Sun, and Venus are strong to the North (of the equator), Saturn and the Moon to the South, and Mercury in both. All the planets are strong in their own vargas, when they have overcome their enemies, and when they are brilliant.
85. They are strong in retrogression, when leaving the Sun, and when they have just risen; the masculine planets are strong at the beginnings of the places, the feminine at the end, and the neuter in the middle.
86. The Moon is strong in the first part of the night, Venus at midnight, and Mars at the end of the night; Mercury is strong in the morning, the Sun at mid-day, Saturn at the end of the day, and Jupiter always.
87. They have their greatest strength in their exaltations, are of medium strength in their mulatrikonas and houses, and have their least strength when aspected by benefit planets or when in their friends’ houses.
88. Jupiter and Mercury are strong in the ascendent, the Sun and Mars in mid-heaven, Saturn in the descendent, and Venus and the Moon in the hypogee.
89. If a month is taken to begin with the first day of the bright paksha, in the first ten tithis the Moon is of medium strength, in the second it is at its greatest strength, and in the third at its least; but it is always strong if it is aspected by benefit planets.
90. The strength of a planet is established in three ways in determining about all actions-according to time, according to position, and according to strong aspects.
91. One finds strength in the ascendent when it is conjoined with or aspected by its own lord or by the lord of the exaltation which is in it, or when it is conjoined with Jupiter, Venus, and Mercury; but the ascendent has little strength in the two twilights.
92. This is said to be the method of determining the strength or weakness of the signs and planets according to the teaching of the Greeks; they say that, of the complete set of influences in horoscopy, there is an enormous number . . . .
93. Through the influence of the places and of the planets in them, which have’ the greatest, medium, the least, or no strength at the times of the natives’ births, men are born with the greatest, medium, or least strength.
94. The planets in the cardines exercise their influence in the first part of life, those in the succedent places in middle age, and those in the cadent places (apoklimas) in old age; (in each group) the order of precedence is determined according to their strengths.
95. At the commencement of life, one says that these are the three (groups) . . . in use; by means of these three, according to their strengths at the time of the child’s birth, one finds his condition (in each period of his life).
96. If the lord of the birth, the lord of the ascendent, or Jupiter is strong and in the ascendent, it exercises its influence at the time (of one) of (the native’s) four ages depending upon which of the four cardines it is in.
97. If the lord of the birth or a planet possessing its qualities and strength is in its exaltation, or in a cardine in its own varga, or in its own house not aspected by malefic planets, then it exercises its influence at the time of birth.
98. Thus they say that, of the many combinations, these are the yogas which produce complete happiness; whereas, if the planets were in their dejections or their enemies’ houses, it would produce complete misery.
99. Planets in signs which rise head-first are strong at the beginnings of their periods; those in signs which rise backwards at the ends; and those in signs which rise both ways exercise their influence in the middles.
100. Those planets which are at the beginning, end, or middle of the ascendant or the sign occupied by the Moon at birth are effective with their good or bad influences at the beginning, end, or middle of their periods respectively.
101. Those navamshas which are at the boundaries of the places at birth are considered to be in them (completely); but, except for the vargottamamshas, all those at the ascendent are considered to be malefic.
102. The benefit planets, when they are in the upacaya places from the ascendent, cause the births of wealthy people; when they are (in the upacaya places) from the Moon, they cause the births of men with many good qualities. The malefic planets, however, (in similar situations cause the births) of lepers, paupers, and men who are lazy.
103. The Moon in the cardines of the Sun produces fools, paupers, and those who are mischievous and without character; in the next (four signs) it causes the birth of wealthy men; and in the cadent signs of those who are born at the heads of their families.
104. If (two) men are born with the ascendent or a cardine of the one in the other’s place, they are mutually helpful-or if they are born under signs (belonging to planets which are) mutually friendly.
105. The planets which are in the second, fourth, fifth, ninth, and twelfth places from another planet’s mulatrikona are its temporary friends, as is the weak planet in its exaltation.
106. The planets which are in the first, third, sixth, seventh, eighth, tenth, and eleventh places are the temporary enemies. I shall call these the “base” (maula) friends and enemies.
107. Jupiter is the friend of the Sun, but the rest are its enemies; all except Mars are the friends of Jupiter; all except the Sun are the friends of Mercury; and all except the Sun and the Moon are the friends of Venus.
