Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 7 · Portents
उत्पाताः
विजात्यं विकृतं वाऽपि षड्भिर्मासैर्म्रियेत वै ।विकृतं वा प्रसूयन्ते परचक्रभयं भवेत् ॥ २४ ॥
In the full Agni Purana this is chapter 263, verse 24.
A birth of another species, or a deformed one: someone may die within six months. Or if they give birth to deformed young, fear of an enemy army would follow.
Simple meaning: An odd or deformed birth can mean a death within six months, or fear of an enemy army.
होमः प्रसूतिवैकृत्ये जपो विप्रादिपूजनम् ।
For odd births, make a fire offering, chant and worship Brahmins. Unyoked carts moving and yoked ones not pulling is a portent.
आकाशे तूर्यनादाश्च महद्भयमुपस्थितम् ।
Trumpet sounds in the sky mean great fear. Wild animals or birds entering a village are also a sign.
अरण्यं यान्ति वा ग्राम्या जलं यान्ति स्थलोद्भवाः ।
Village animals going to the forest, land and water animals swapping places, or jackals at a palace gate are signs.
