Simple meaning: A sow, a koel and creatures with male names are good on the left. Female names are good on the right.
कपिश्रीकर्णपिप्पीका रुरुश्येनाश्च दक्षिणाः ।
Female-named creatures and hawks are good on the right. Saying the names of a snake, hare or boar is good.
ततः संदर्शनं नेष्टं प्रतीपं वानरर्क्षयोः ।
Naming them is good, seeing them is not. A strong omen met on a journey gives its result that day.
भवेत्तस्य फलं वाच्यं तदेव दिवसं बुधैः ।
The wise should tell the result for that same day. Drunk or hungry animals do not count.
