ग्रहचारः केतवश्च
घटोक्ष्णस्तु समः कर्कचापयोः शरसन्निभः ।चापवत्कौर्महर्योश्च शूलवत्तुलकर्कयोः ॥ १९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 19.
The Moon's horns are level in Aquarius and Taurus. In Cancer and Sagittarius it looks like an arrow. In Scorpio and Leo it looks like a bow. In Libra and Cancer it looks like a spear. (Our text is unclear here: Cancer is named twice; the second is likely Virgo.)
Simple meaning: The rising Moon can look level, like an arrow, a bow or a spear, depending on its sign.
विपरीतोदितश्चंद्रो दुर्भिक्षकलहप्रदः ।
A wrongly rising Moon brings famine and quarrels.
अग्निप्रदस्तेयचरवनसर्पविनाशकृत् ।
A Moon south of these stars may harm thieves, forests and snakes. South of Vishakha and Anuradha it is bad.
मध्यमः पितृदैवत्ये द्विदेवे सौम्यगः शशी ।
A Moon north of Magha and Vishakha is middling. Joining the stars from Revati early is good.
