उत्पाताः
नद्यो ह्रदप्रस्रवणा विरसाश्च भवन्ति च ।सलिलाशयवैकृत्ये जप्तव्यो वारुणो मनुः ॥ २१ ॥
In the full Agni Purana this is chapter 263, verse 21.
Rivers, lakes and springs do this, and they turn tasteless. For a disorder of water bodies, the Varuna mantra should be chanted.
Simple meaning: Rivers, lakes and springs moving or turning tasteless is a portent. Chant the Varuna mantra to calm it.
अकालप्रसवा नार्यः कालतो वाऽप्रजास्तथा ।
Women giving birth out of season, staying childless in season, or having odd births or twins are portents.
विजात्यं विकृतं वाऽपि षड्भिर्मासैर्म्रियेत वै ।
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.
