विवाहः
एकाधिपे मित्रभावे शुभदं पाणिपीडनम् ।द्विर्द्वादशे त्रिकोणे च न कदाचित्षडष्टके ॥ ५०४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 504.
When the two signs have one lord, or their lords are friends, the wedding is good. That holds in the 2nd-12th and the 5th-9th count too. In the 6th-8th it is never good.
Simple meaning: Same or friendly sign lords make 2-12 and 5-9 good. A 6-8 count is never good.
अश्वेभमेषसर्पाहिह्योतुमेषोतुमूषकाः ।

श्वैणं बभ्ररगं मेषवानरौ सिंहवारणम् ।
