Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 7 · Portents
उत्पाताः
अहर्क्षवैकृतं दिव्यमान्तरी(रि)क्षं निबोध मे ।उल्कापातश्च दिग्दाहः परिवेशस्तथैव च ॥ १२ ॥
In the full Agni Purana this is chapter 263, verse 12.
The heavenly kind is a disturbance of the day and the stars. Learn the middle-air kind from me: falling meteors, burning of the sky quarters, and halos.
Simple meaning: Heavenly signs disturb the day and stars. Falling meteors, burning skies and halos are signs of the middle air.
गन्धर्वनगरं चैव वृष्टिश्च विकृता च या ।
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.
