यात्रा शकुनाश्च
अज्ञातजन्मनां नृणां फलाप्तिर्घुणवर्णवत् ।प्रश्नोदयनिमित्ताद्यैस्तेषामपि फलोदयः ॥ ६२१ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 621.
For people with unknown births, results come like the worm-eaten letter, by chance. For them too, results come through prashna (question chart), the rising sign, omens and the like.
Simple meaning: 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.
न मंदेंदुदिने प्राचीं न व्रजेद्दक्षिणं गुरौ ।
Avoid these directions on these weekdays.
