Chapter 8 · Marriage
विवाहः
अकालजा भवंत्येते विद्युन्नीहारवृष्टयः ।दोषाय मंगले नूनमदोषायैव कालतः ॥ ४८१ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 481.
Lightning, mist and rain that come out of season are a fault in a good act. In their own season they are no fault at all.
Simple meaning: Lightning, mist and rain out of season spoil a good act. In season they do no harm.
बृहस्पतिः केंद्रगतः शुक्रो वा यदि वा बुधः ।
Jupiter, Venus or Mercury in a corner house removes a heap of faults, even alone.
तिर्यक्पंचोर्द्ध्वगाः पञ्च रेखा द्वे द्वे च कोणयोः ।
Draw a wheel of five lines across and five up, and start the stars at the north-east corner.
भान्यत्र साभिजित्येकरेखाखेटेन विद्धभम् ।
Place the stars on the wheel. A planet pierces a star on its line. Planets also kick the day's star.
