Chapter 8 · Marriage
विवाहः
उग्रं च संधित्रितयं गंडातं त्रिविधं महत् ।लग्नाभिमुखयोः पापग्रहयोर्ऋजुवक्रयोः ॥ ४५० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 450.
Fierce too is the triple junction. Gandanta (the edge-point between signs) is threefold and great. When two bad planets, one straight and one retrograde, face the lagna (rising sign),
Simple meaning: Gandanta has three kinds. Two bad planets facing the lagna make a worse fault.
सा कर्तरीति विज्ञेया दंपत्योर्गलकर्तरी ।
Bad planets on both sides of the lagna cut it. Do not use such a lagna.
अपि सौम्यग्रहैर्युक्तं गुणैः सर्वैः समन्वितम् ।
The Moon in the 6th, 8th or 12th spoils a lagna even when it looks good.
तल्लग्नं वर्जयेद्यत्नाज्जीवशुक्रसमन्वितम् ।
Drop such a lagna even with Jupiter and Venus, and whatever the Moon's sign.
