क्रियणतौलिककर्काद्या मेषादिषु नवांशकाः ।स्वभाद्वादशभागेशाः षडर्गं राशिपूर्वकम् ॥ ५ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 5.
The navamsha (one-ninth part of a sign) counts start from Aries, Capricorn, Libra and Cancer. This runs in turn for Aries and the signs after it. The lords of the dvadashamsha (one-twelfth part of a sign) are counted from the sign itself. The shadvarga (six divisions of a sign) starts with the sign. (Our text is unclear here: the name for Capricorn is damaged in print.)
Simple meaning: Navamsha counting starts from Aries, Capricorn, Libra and Cancer. The twelfth parts are counted from the sign itself.
गोजाश्च कर्कयुग्मेन रात्र्याख्या पृष्ठकोदयाः ।
Taurus, Aries, Cancer and Gemini are night signs. The rest are day signs. Pisces rises both ways.
पुमान् स्त्री च क्लीबश्चरस्थिरद्विःस्वभावकाः ।
The signs are male, female or neuter, moving, fixed or dual. Aries and the others point to directions starting from the east.
अजोक्षेणांगनाकीटझषजूका इनादितः ।
The Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn are strongest in Aries, Taurus, Capricorn, Virgo, Cancer, Pisces and Libra.
