स्वोच्चेष्वार्की तथा ज्यारैरुक्तैकांगे नृपाधिपाः ।लग्ने वर्गोत्तमेऽब्जे वा चतुरादिग्रहेक्षिते ॥ १७० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 170.
Saturn, Jupiter and Mars stand in their high signs. One of them is in the lagna (rising sign). Then the person rules over kings. So too if the lagna or the Moon is vargottama (same sign in the chart and its navamsha). That lagna or Moon must have the looks of four or more planets.
Simple meaning: Saturn, Jupiter and Mars exalted, or a vargottama lagna or Moon seen by four planets, make a great king.
द्वाविंशभूपास्तुंगेसृक्चापेर्केन्दूयमस्तनौ ।
Mars exalted with Sun and Moon in Sagittarius, or the Sun exalted rising with Jupiter in the 10th, makes a king.
यमेंदुतुंगगौ लग्ने षष्ठेऽर्कज्ञौ तुलाजगौ ।
Saturn and the Moon exalted, Venus and Mars in their own signs, and Jupiter rising in Cancer make a king.
आर्के जीवे तनौ वापि नृपोऽथोः कुजभास्करौ ।
The Sun or Jupiter rising, or Mars and Sun in the 5th with three planets in the 4th, make a king.
