In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 555.
The thirty-two parts next to the wall, all round, are the pishacha (goblin) parts. Starting a house in one can bring sorrow, grief and fear.
Simple meaning: There are 32 parts along the wall. Starting a house in the goblin part can bring sorrow and fear.
शेषांशाः स्युश्च निर्माणे पुत्रपौत्रधनप्रदाः ।
The other parts bring sons and wealth. The plot's veins are lines from directions and corners.
ब्रह्मभागाः पिशाचांशाः शिराणां यत्र संहतिः ।
The middle parts, the goblin parts and where the veins cross are the plot's weak spots.
मर्माणि संधयो नेष्टाः स्वस्थेऽप्येवं निवेशने ।
Avoid vital points and joints. Good months are Margashirsha, Phalguna, Vaishakha, Magha, Shravana and Kartika.
