जातकम् १
अयनक्षणघस्रर्तुमासार्द्धशरदो रवेः ।कटुतिक्तक्षारमिश्रमधुराम्लकषायकाः ॥ २४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 24.
From the Sun on, the time spans are these. A half-year, a moment, a day, a season, a month, a fortnight and a year. The tastes, in the same order, are pungent, bitter, salty, mixed, sweet, sour and astringent.
Simple meaning: 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.
स्वोच्चत्रिकोणगेहा प्रनवांशैस्थानजं बलम् ।
A planet is strong in its high sign, own sign and own navamsha. It also gets strength from a direction.
