Chapter 8 · Marriage
विवाहः
झषालिकर्कटा विप्रास्तदूर्ध्वाः क्षत्रियादयः ।पुंवर्णराशेः स्त्रीराशौ सतिहीने यथाशुभम् ॥ ५०८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 508.
Pisces, Scorpio and Cancer are Brahmin signs. The signs after them are Kshatriya and the rest. Say the woman's sign is lower in varna (caste match) than the man's. Then it is good.
Simple meaning: Signs are grouped by caste. A woman's sign lower than the man's in caste is good.
चतुस्त्रिद्व्यंघ्रिभोत्थायाः कन्यायाश्चाश्विभात्क्रमात् ।
The girl's star decides how the nadi is counted: in three, four or five parts.
गणयेत्संख्यया चैकनाड्यां मृत्युर्न पार्श्वयोः ।
The same nadi may put life at risk, not the two side ones. Four kinds of wedding are named.
उक्तकाले तु कर्तव्याश्चत्वारः फलदायकाः ।
The first four kinds of wedding need the right time. The other four can be done at any time.
