जातकम् १
त्र्याशत्रिकोणतुर्याष्टसप्तमान्येन वृद्धितः ।सौरेज्यारापरे पूर्णे क्रमात्पश्यंति नारद ॥ २३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 23.
Planets see the 3rd and 10th, the 5th and 9th, the 4th and 8th, and the 7th. Their sight grows step by step in that order. Saturn, Jupiter and Mars see those places fully, in that order, O Narada.
Simple meaning: 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.
वींद्वर्का विकुजेंद्वर्काः सुहृदोऽन्ये रवेर्धृताः ।
Planets in the 2nd, 3rd, 4th, 10th, 11th or 12th from each other are friends for the moment.
