दुर्मुहूर्तो वारदोषः खार्जूरिकसमाङ्घ्रिभम् ।ग्रहणोत्पातभं क्रूरविद्धर्क्षं क्रूरसंयुतम् ॥ ४३८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 438.
A bad muhurta (48 minutes). The weekday fault. A star on the same line in the Kharjura chakra. The star of an eclipse or portent. A star pierced by bad planets. A star joined with bad planets.
Simple meaning: More faults: a bad hour, a bad weekday, and stars spoiled by line, eclipse or bad planets.
कुनवांशो महापातो वैधृतिश्चैकविंशतिः ।
The last faults are a bad navamsha, Mahapata and Vaidhriti. The five almanac parts come next.
पंचांगमस्य शुद्धिस्तु पंचांगशुद्धिरीरिता ।
A lagna with a fault in any almanac part is worth nothing.
त्यजेत्पंचैष्टिकं चापि विषसंयुक्तदुग्धवत् ।
Drop the five-fold fault. The lagna and its navamsha should be seen or joined by their own lords.
