बलप्रस्थानयोः सर्वे पुरस्तात्संघचारिणः ।जयावहा विनिर्दिष्टाः पश्चान्निधनकारिणः ॥ २० ॥
In the full Agni Purana this is chapter 231, verse 20.
At an army's march or a setting out, all creatures that move in flocks bring victory when in front. Behind, they bring death.
Simple meaning: In front of a marching army they bring victory. Behind it they bring death.
गृहाद्गम्य यदा चासो(षो) व्याहरन्पुरतः स्थितः ।
An Indian roller calling in front means an insult from the king. On the left, a quarrel and a meal.
याने तद्दर्शनं शस्तं सव्यमङ्गस्य वाऽप्यथ ।
Seeing an Indian roller on a journey is good. A peacock's broken cry warns of thieves.
प्रयातस्याग्रतो राम मृगः प्राणहरो भवेत् ।
A deer in front of a traveler can mean danger to his life. Bears, jackals, tigers and cats are also named.
