In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 568.
Take the months from Bhadrapada, three at a time, in order. The Vastu man has his head to the east and the other directions in turn. He lies on his left side. He moves anticlockwise.
Simple meaning: The Vastu man turns through the directions every three months, starting from Bhadrapada.
चराह्वयो वास्तुपुमान् चरत्येवं महोदरः ।
Make the house face the same way as the Vastu man faces.
प्रतिकूलमुखं गेहं रोगशोकभयप्रदम् ।
A house facing against the Vastu man can bring illness, sorrow and fear.
वृत्येटिका स्वर्णरेणुधान्यशैवलसंयुतम् ।
Place a brick with gold dust, grain and moss in a pit in the middle of the house.
