Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 7 · Portents
उत्पाताः
गन्धर्वनगरं चैव वृष्टिश्च विकृता च या ।चरस्थिरभवं भूमौ भूकम्पमपि भूमिजम् ॥ १३ ॥
In the full Agni Purana this is chapter 263, verse 13.
Gandharva city (a mirage city in the sky), and rain that is not normal. On the earth: what is born of moving and fixed things, and earthquakes, born of the earth.
Simple meaning: A mirage city, odd rain, strange events with living or fixed things, and earthquakes are portents.
सप्ताहाभ्यन्तरे वृष्टावद्भुतं निष्फलं भवेत् ।
Rain within seven days cancels the portent. Without a peace ritual it can bring fear within three years.
देवतार्चाः प्रनृत्यन्ति वेपन्ते प्रज्वलन्ति च ।
Images of the gods dance, shake, blaze, cry, weep, sweat or laugh.
न दीप्यते चेन्धनवांस्तद्राष्ट्रं पीड्यते नृपैः ।
A fire that will not blaze even with fuel means kings will oppress the land. Fire mantras are the remedy.
