जातकम् १
सिंहोक्षाविस्रश्चतौलिकुंभाः सूर्यात्रिकोणभम् ।चतुरस्रं तूर्यमृत्युत्रिकोणं नवपंचमम् ॥ १० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 10.
From the Sun on, the mulatrikona (a planet's strong own-sign part) signs are these. Leo, Taurus, Aries, a damaged word, Libra and Aquarius. The 4th and 8th are the square houses. The 9th and 5th are the trikona (luck house) places. (Our text is unclear here: one sign name is damaged and one is missing.)
Simple meaning: Sun, Moon and Mars have strong parts in Leo, Taurus and Aries. The 5th and 9th are luck houses.
रिःफाष्टषट्कं त्रिकभं केंद्रं प्राक्तुर्यसप्तखम् ।
The 6th, 8th and 12th are bad places. The 1st, 4th, 7th and 10th are corner houses.
केंद्रात्परं पणफरमापोक्लिममतः परम् ।
After the corner houses come the succeeding houses, then the falling houses. The signs also have colours, from red upward.
चित्रः कृष्णः पीतपिंगौ बभ्रुः स्वच्छः प्रभाक्रियात् ।
The rest of the signs have colours too: variegated, black, yellow, tawny, brown and clear.
