कालमानं मुहूर्ताङ्गानि च
संक्रांतेः परतो भानुर्भुक्त्वा यावद्भिरंशकैः ।रवेरयनसंक्रांतिस्तदा तद्राशिसंक्रमात् ॥ २६७ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 267.
After its sankranti (the Sun's entry into a sign), the Sun covers some number of degrees. Then comes the Sun's turning-point entry, counted from its entry into that sign. (Our text is unclear here: how many degrees.)
Simple meaning: After the Sun enters a sign and covers some degrees, the next turn of its course follows.
संक्रांतिग्रहगर्क्षंवा जन्मन्युभयपार्श्वयोः ।
The star of a sankranti or an eclipse next to the birth star is not wanted for vows and marriage.
ताराबलेन शीतांशुर्बलवांस्तद्वशाद्रविः ।
Star count strength makes the Moon strong. Through the Moon, the Sun and others become strong.
शुभोऽर्को जन्मतस्त्र्यायदशषट्सु मुनीश्वर ।
The Sun is good in the 3rd, 11th, 10th and 6th from the Moon, unless blocked.
