19.4

horā īśa ṛkṣa dala āśritaiḥ śubha karo dṛṣṭaḥ śaśī tad gatas try aṃśe tat patibhiḥ suhṛd bhavanagair vā vīkṣitaḥ śasyate/
yat proktaṃ prati rāśi vīkṣaṇa phalaṃ tad dvādaśa aṃśe smṛtaṃ sūrya udyair avalokite api śaśini jñeyaṃ nava aṃśeṣv ataḥ//(śā vi)

When the Moon is aspected by planets stationed in the half-sign of the lord of the horā, it brings good fortune; situated in a decan, it is praised when aspected by the lords of those [decans] or by planets in friendly signs; / whatever result was stated for the aspects in each zodiacal sign, that is remembered in the dvādaśāṃśa; likewise, when the Moon is aspected by the Sun and the rest, it should be known in the navāṃśas henceforth.
