यात्रा शकुनाश्च
अथो यात्रा नृपादीनामभीष्टफलसिद्धये ।स्यात्तथा तां प्रवक्ष्यामि सम्यग्विज्ञातजन्मनाम् ॥ ६२० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 620.
Now I will explain the journey of kings and others, so that the wished results come true. It is for those whose birth time is well known.
Simple meaning: A journey can give the wished result when the birth time is well known.
अज्ञातजन्मनां नृणां फलाप्तिर्घुणवर्णवत् ।
If the birth time is not known, results come from the question chart, the rising sign and omens.
षष्ठ्यष्टमीद्वादशीषु रिक्तामापूर्णिमासु च ।
Travel on these moon days can bring poverty and loss.
मैत्रादितींद्वर्कांत्याश्विहरितिष्यवसूडुषु ।
These nine stars are good for travel, unless they are the 1st, 3rd, 5th or 7th from your birth star.
