जातकम् १
लग्नांशाद्ग्रहयुग्दृष्ट्वा वर्णान्बलयुताद्वदेत् ।दृक्समानप्रमाणांश्च इष्टे रेखां स्मरस्थितैः ॥ ३५ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 35.
Take the navamsha (one-ninth part of a sign) of the lagna (rising sign). Or take the strongest planet joined to it or seeing it. Tell the creature's colours from that. Tell as many colours as there are planets that see it. Planets in the 7th give a stripe on the back. (Our text is unclear here: the word read as 'on the back' is damaged.)
Simple meaning: An animal's colours come from the lagna's navamsha or the strongest planet tied to it. The 7th gives stripes.
विप्रलैस्तनुचंद्रेज्यार्कैस्तरूणां जनिं वदेत् ।
A weak lagna, Moon, Jupiter and Sun point to trees. The navamsha shows land or water trees.
स्थलांबु च पतिः खेटो लग्नाद्यावन्मिते गृहे ।
The number of trees is told by how far the planet stands from the lagna.
अंतःसारा रवौ सौरे दुर्भगाः क्षीरिणो विधौ ।
Each planet shows what kind of tree: the Sun hard wood, the Moon milky, Mars thorny.
