जातकम् १
हेमकांस्यायसी त्र्यंशैः शिशिराद्याः प्रकीर्तिताः ।सौरशुक्रारचंद्रज्ञगुरुषूद्यत्सु च क्रमात् ॥ २२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 22.
Gold, bronze and iron end the list of metals. The seasons from Shishira (late winter) on are named by the drekkana (one-third part of a sign). They go in turn with Saturn, Venus, Mars, the Moon, Mercury and Jupiter, when these rise.
Simple meaning: The six seasons go with Saturn, Venus, Mars, Moon, Mercury and Jupiter, read from what is rising.
त्र्याशत्रिकोणतुर्याष्टसप्तमान्येन वृद्धितः ।
Planets see the 7th fully and some houses partly. Saturn, Jupiter and Mars see extra houses fully.
अयनक्षणघस्रर्तुमासार्द्धशरदो रवेः ।
From the Sun on, each planet has a time span and a taste.
त्रिकोणात्सांत्यधाधर्मायुः सुखखोद्यपः सुहृत् ।
A planet's friends are counted from its own strong sign. The verse then names each planet's friends.
