In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 307.
The Moon's strength is the support. The other planets are what it holds. What is held rests on the support and stays in place.
Simple meaning: The Moon's strength holds up the other planets.
चेदिंदुः शुभदः सर्वे ग्रहाः शुभफलप्रदाः ।
If the Moon is good, all planets give good. If bad, they give bad.
लग्नस्याभ्युदिता येंशास्तेष्वंशेषु स्थितो ग्रहः ।
A planet in the risen part of the rising sign acts as a 1st house planet.
दोषाल्पत्वं गुणाधिक्यं बहु संततमिष्यते ।
Look for few faults and many good points. No time is free of faults.
