वास्तु गृहप्रवेशश्च
कलत्रहानिर्निःसत्त्वं हानिर्द्धान्यधनागमः ।संपद्वृद्धिर्मासभीतिरामयं दिशि शीतगोः ॥ ५५२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 552.
North, the Moon's side: grief over a wife, weakness, loss, gain of grain, gain of wealth, growth of riches, fear, and illness. (Our text is unclear here: the word before 'fear' reads 'masa', month.)
Simple meaning: The eight north doors may bring grief over a wife, loss, wealth or illness, in order.
Classical view, not medical advice.
एवं गृहादिषु द्वारविस्ताराद्विगुणोच्छ्रितम् ।
A door should be twice as high as it is wide. Place it on the west or south.
प्राकारांतः क्षितिं कुर्यादेकाशीतिपदं यथा ।
Divide the ground into 81 squares. The middle nine are Brahma's place and are not for building.
द्वात्रिंशदंशाः प्राकारसमीयांशाः समंततः ।
There are 32 parts along the wall. Starting a house in the goblin part can bring sorrow and fear.
