यात्रा शकुनाश्च
वासिष्ठकाश्यपेयात्रिभारद्वाजाः सगौतमाः ।एतेषां पञ्चगोत्राणां प्रतिशुक्रो न विद्यते ॥ ६३६ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 636.
The Vasishtha, Kashyapa, Atri, Bharadvaja and Gautama gotra (clan line) people: for these five clan lines there is no pratishukra (Venus standing in front of the traveler).
Simple meaning: These five clan lines have no fault of Venus in front.
एकग्रामे विवाहे च दुर्भिक्षे राजविग्रहे ।
This Venus fault does not count in these cases.
नीचगोऽरिगृहस्थो वा वक्रगो वा पराजितः ।
Venus low, in an enemy's house, backward or beaten can break the journey. Venus high brings victory.
स्वाष्टलग्नेष्टराशौ वा शत्रुभात्त्वष्टमेपि वा ।
A journey rising sign that is the 8th from your birth chart can put life at risk, the verse says.
