ग्रहचारः केतवश्च
चत्वारिंशत्क्रमात्रिंशद्रवींदू भूसुतो नव ।पंचदशैकादशभिर्दिवसैः शशिनंदनः ॥ ४९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 49.
In order, Mercury is seen for forty days, then thirty. Two more counts are printed as 'the Sun and Moon' and 'the son of the earth'. Then come nine, fifteen and eleven days. (Our text is unclear here: two of the seven counts are garbled.)
Simple meaning: Mercury stays seen a set number of days in each of its seven paths.
प्राकृतायां गतः सौम्यः क्षेमारोग्यसुभिक्षकृत् ।
Mercury's natural path brings welfare and health. The mixed and short paths are middling.
वैशाखे श्रावणे पौषे आषाढेऽभ्युदितो बुधः ।
Mercury rising in some months brings bad results to the world. In other months it is good.
इषोर्जमासयोः शस्त्रदुर्भिक्षाग्निभयप्रदः ।
Mercury rising in Ashvina or Kartika brings weapon, famine and fire fear. A silver-white Mercury is best.
