Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 5 · Omens
शकुनानि
प्रतिलोमास्तथा राम खरश्च विकृतस्वनः ।वामः कपिञ्जलः श्रेष्ठस्तथा दक्षिणसंस्थितः ॥ २४ ॥
In the full Agni Purana this is chapter 231, verse 24.
Going the wrong way, O Rama, they likewise threaten life. So does a donkey with a harsh cry. A francolin on the left is best, and so is one standing on the right.
Simple meaning: These animals going the wrong way can mean danger to life. A francolin on either side is good.
पृष्ठतो निन्दितफलस्तित्तिरिस्तु न शस्यते ।
A partridge is not praised. Deer and boars that move from left to right bring gain.
भवन्त्यर्थकरा नित्यं विपरीता विगर्हिताः ।
Deer and boars moving left to right bring gain. The reverse is bad.
वाञ्छितार्थकरा ज्ञेया दक्षिणाद्वामतो गताः ।
Moving from right to left they bring the wished-for result. Jackals and house lizards begin the next list.
