Agni Purana (Jyotisha Selections) · by Vyasa
Chapter 5 · Omens
शकुनानि
वामोऽनुलोमगः श्रेष्ठो मध्यमो दक्षिणः स्मृतः ।प्रतिलोमगतिर्वामो गमनप्रतिषेधकृत् ॥ १० ॥
In the full Agni Purana this is chapter 232, verse 10.
On the left and moving the right way, it is best. On the right it is called middling. On the left and moving the wrong way, it stops the trip.
Simple meaning: A crow on the left going the right way is best. On the right, middling. Going wrong, it stops the trip.
निवेदयति यात्रार्थमभिप्रेतं गृहे गतः ।
A crow in the house shows the trip's aim will be met. One on one foot staring at the Sun brings fear.
कोटरे वासमानश्च महानर्थकरो भवेत् ।
A crow in a tree hollow can bring great harm. On salty ground it is not good. A muddy one is good.
अमेध्यपूर्णवदनः काकः सर्वार्थसाधकः ।
A crow with filth in its beak brings success. Other birds read like the crow.
