कालमानं मुहूर्ताङ्गानि च
गोयुग्मकर्ककन्यांत्यतुलाचापधराः शुभाः ।शुभर्क्षत्वाशुभासत्य इतरा पापराशयः ॥ ३०३ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 303.
Taurus, Gemini, Cancer, Virgo, Pisces, Libra and Sagittarius are good signs. The others are bad signs. (Our text is unclear here: a short phrase between the two lists.)
Simple meaning: Seven signs are good and the others are bad.
ग्रहयोगावलोकाभ्यां राशिर्धत्ते ग्रहोद्भवम् ।
A sign gives a planet's result through joining or looking. Without them it acts by its own nature.
आदौ संपूर्णफलदं मध्ये मध्यफलप्रदम् ।
A rising sign gives full results at its start and small ones at its end.
सर्वत्र प्रथमं लग्नं कर्तुश्चंद्रबलं ततः ।
First check the rising sign, then the doer's Moon. A strong Moon makes the planets strong.
