v6.c82.412

The *bala* (strength) of planets is of four kinds (arises in four ways) viz place, direction, activity (*ceṣṭā*), time. A planet is powerful in its position when it is in its own house or in exaltation (*ucca*) or in its friend's house or in its *trikoṇa* or *navāṁśa*. This is *sthānabala*. Mercury and Jupiter are powerful in the east (i e when they are in the *lagna*), the Sun and Mars in the south (i. e. in the 10th house), Saturn in the West (i e. 7th house), the Moon and Venus are powerful in the north (i e. 4th house). This is *digbala*. The Sun and Moon are powerful in the northern *ayana*⁸⁷² (i. e. in the six *rāśis* from Capricorn); the remaining planets are powerful when they are retrograde or in conjunction with the Moon or when there is a fight (between planets other than the Sun and the Moon), the one to the north being more powerful. Garga quoted in the Adbhutasāgara says that *grahayuddha* (fight of planets) occurs when one planet occults the other, or when it slightly covers, or when the light of one throws into the background the light of another or when one planet is to the left of the other slightly. This is *ceṣṭābala*. The Moon, Mars and Saturn are powerful at night, Mercury is powerful both by day and night, and others are powerful by day; *krūra* and *saumya* planets are respectively powerful in the dark half and bright half of the month, a planet is powerful in the year of which he is the lord, or on his own week-day or *horā* or in the month of which he is the lord This is *kālabala*.⁸⁷³ Yavaneśvara says 'for ten days from the 1st tithi of the bright half the Moon is of middling power but in the next period of ten days (from śukla 11th to kṛṣṇa) 5th Moon's power is highest and in the last ten days (from kṛṣṇa 6th to *amāvāsyā*) the Moon has slight power, but if Moon has an aspect with saumya planets (Jupiter &c.) he is always powerful
