ग्रहचारः केतवश्च
मध्यमः पितृदैवत्ये द्विदेवे सौम्यगः शशी ।अप्राप्यपौष्णभाद्रौद्रामदुक्षाविशशी शुभः ॥ २२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 22.
In Magha and Vishakha, a Moon on the north side is middling. The Moon is good when it joins the stars from Revati before reaching them. (Our text is unclear here: the words after Revati are garbled; they seem to name Ardra.)
Simple meaning: A Moon north of Magha and Vishakha is middling. Joining the stars from Revati early is good.
मध्यगोद्वारदक्षाणि अतीत्य नववासवात् ।
The Moon meets some stars in the middle, others after passing. Six stars count as half-stars.
ध्रुवादितिद्विदैवाः स्युरध्यर्द्धाश्चापराः समाः ।
Some stars count as one and a half and others as equal. A raised south horn is bad.
कार्यहानिः कार्यवृद्धिर्हानिर्वृद्धिर्यथाक्रमम् ।
A broad Moon brings plenty of food. A narrow Moon can bring loss.
