In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 500.
This is to be known as the human gana (temper group). The other is the god group: Shravana, Punarvasu, Hasta, Swati, Revati, Anuradha, Ashvini, Pushya and Mrigashira.
Simple meaning: That was the human group. The god group is Shravana, Punarvasu, Hasta, Swati, Revati, Anuradha, Ashvini, Pushya and Mrigashira.
रक्षोगणः पितृत्वाष्ट्रद्विदैवाग्नींद्रतारकाः ।
The demon group is Magha, Chitra, Vishakha, Krittika, Jyeshtha, Dhanishtha, Shatabhisha, Mula and Ashlesha.
दंपत्योर्जन्मभे चैकगणे प्रीतिरनेकधा ।
Same group means much love. God and human is middling. A demon with another group may put life at risk.
मृत्युः षष्ठाष्टके पंचनवमे त्वनपत्यता ।
A 6-8 count may risk life, 5-9 may bring no children, 2-12 poverty. Other counts give the best love.
