यात्रा शकुनाश्च
अधियोगो भवेद्वाभ्यां त्रिभिर्योगाधियोगकः ।योगेऽपि यायिनां क्षेममधियोगे जयो भवेत् ॥ ६५४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 654.
With two of them it is an adhiyoga. With three it is a yogadhiyoga. In a yoga (planet combination) of one, travelers are safe. In an adhiyoga, there is victory.
Simple meaning: One good planet keeps the traveler safe. Two bring victory.
योगाधियोगे क्षेमं च विजयार्थविभूतयः ।
Three good planets bring safety, victory and wealth. The next verse gives the result of another placement.
रणे गतस्य भूपस्य जयलक्ष्मीः प्रमाणिका ।
With the Moon in the 10th, Saturn in the 6th and Sun in the 1st, a king going to war wins.
गतस्याग्रे वैरिचमूर्वह्नौ लाक्षेव लीयते ।
With the planets of the last verse so placed, the enemy army may melt away before the king.
