वास्तु गृहप्रवेशश्च
मृदुध्रुवक्षिप्रभेषु रिक्तामावर्जिते दिने ।व्यर्कारचरलग्नेषु पापे चाष्टमवर्जिते ॥ ५७७ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 577.
Pick a soft, fixed or quick nakshatra (star). The day must not be a rikta (empty tithi) or the new moon. It must not be a Sunday or Tuesday. The lagna (rising sign) must not be a moving sign. No bad planet may be in the 8th house.
Simple meaning: Choose a good star and a good weekday, avoid empty days, and keep the 8th house free of bad planets.
नैधने शुद्धिसंयुक्ते शुभलग्ने शुभांशके ।
Set the peg in a good rising sign, with a clean 8th house and good planets looking at it.
ताः पुनः षड्विधाः शालाः प्रत्येकं दशषड्विधाः ।
Halls come in six kinds, each with sixteen forms. Seven names are given here.
सुमुखं दुर्मुखं क्रूरं शत्रुं स्वर्णप्रदं क्षयम् ।
Nine more hall names are given. Vijaya is the sixteenth.
