Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 8 · Marriage
विवाहः
एकार्गलांघ्रितुल्यं यत्तल्लग्नं च विवर्जयेत् ।अपिशुक्रेज्यसंयुक्तं विषसंयुक्तदुग्धवत् ॥ ४७१ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 471.
Avoid the lagna (rising sign) that matches the ekargala (single-bolt fault) quarter, even if Venus and Jupiter are with it. It is like milk mixed with poison.
Simple meaning: Avoid a lagna with the single-bolt fault, even with Venus and Jupiter. It is like milk with poison.
ग्रहणोत्पातभं त्याज्यं मंगलेषु ऋतुत्रयम् ।
Skip a star hit by an eclipse or omen. A star the Moon has just left is like burnt wood.
मंगलेषु त्यजेत्खेटैर्विद्धं च क्रूरसंयुतम् ।
Avoid a star that is pierced or joined by bad planets. It is like pure food spoiled by one drop of liquor.
पाद एव शुभैर्विद्धमशुभं नैव कृत्स्नभम् ।
A star pierced by good planets is spoiled only in one quarter. One hit by cruel planets is not good at all.
