यात्रा शकुनाश्च
स्वाष्टलग्नेष्टराशौ वा शत्रुभात्त्वष्टमेपि वा ।तेषामीशस्थराशौ वा यातुर्मृत्युर्न संशयः ॥ ६३९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 639.
In these cases there is a risk to the traveler's life. The lagna (rising sign) is the 8th from his own birth lagna, or the 8th from his own sign. Or it is the 8th from the enemy sign. Or it is the sign where their lords stand.
Simple meaning: A journey rising sign that is the 8th from your birth chart can put life at risk, the verse says.
जन्मेशाष्टमलग्नेशौ मिथो मित्रे व्यवस्थितौ ।
If the birth sign lord and the 8th sign lord are friends, the 8th sign fault goes away.
क्रूग्रहेक्षितो युक्तो द्विःस्वभावोऽपि भंगदः ।
A dual sign with bad planets can break the journey. A fixed rising sign is not good, even with good planets.
वस्वंत्यार्द्धादिपंचर्क्षे संग्रहं तृणकाष्ठयोः ।
In the last five stars, do not store grass or wood, go south, make a bed or roof the house.
