शुभलग्ने शुभांशे च नैधने शुद्धिसंयुते ।लग्ने तु निधने सौम्यैः संयुते वा निरीक्षिते ॥ ३७० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 370.
Do it in a good lagna (rising sign) and a good navamsha (one-ninth part of a sign). Keep the 8th house clean. Or the lagna and 8th house are joined or looked at by good planets.
Simple meaning: Choose a good rising sign and navamsha, a clean 8th house, and help from good planets.
इष्टैर्जीवार्कचंद्राद्यैः पंचभिर्बलिभिर्ग्रहै ।
Five strong planets are best. Four strong, well-placed ones also work.
ईक्षन्नैवात्रैकविंशमहादोषविवर्जिते ।
Choose a time free of the twenty-one great faults. Any sign is good with good planets joining or looking.
शुभनवांशकगता ग्राह्यास्ते शुभराशयः ।
Take signs in a good navamsha. Never take a Cancer navamsha, even with good planets looking.
