13.3

hitvā arkaṃ sunaphā anaphā durudhurāḥ sva antya ubhayasthair grahaiḥ śīta aṃśoḥ kathito anyathā tu bahubhiḥ kemadrumo anyais tv asau/
kendre śīta kare atha vā graha yute kemadrumo na iṣyate ke cit kendra nava aṃśakeṣu ca vadanty uktiḥ prasiddhā na te//(śā vi)

Leaving out the Sun, Sunaphā, Anaphā, and Durudhurā are formed by planets occupying the second, the twelfth, and both [such houses] from the Moon; / but otherwise, by many an authority Kemadruma is declared. By others, however, / Kemadruma is not accepted when the Moon is in a cardinal house or conjoined with a planet; / some also speak of it in terms of cardinal houses and navāṃśas, but their statement is not celebrated.
