In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 59.
Seen in the daytime, Jupiter may bring a risk to the king's life, illness, or harm to the kingdom. The body of the year is Krittika and Rohini.
Simple meaning: Seen in daylight, it can bring danger to a king, illness and harm to the land.
Classical view, not medical advice.
नाभिस्त्वापाठ्युगलमाद्री हृत्कुसुमं मघा ।
When a cruel planet strikes the year's body, famine, fire and wind can be feared.
नाभ्यां क्षुत्तृड्भयं पुष्ये सम्यङ्मूलफलक्षयः ।
Strikes on the year's navel, flower or heart risk hunger, fruit loss or a ruler's life. Good planets help.
शस्यवृद्धिः प्रजारोग्यं युद्धं जीवात्यवर्षणम् ।
Jupiter's results run star by star: crops, health, war, drought, then joy for cows, kings and women.
