Say lightning, a meteor or a thunderbolt comes at sunrise or sunset. Then know there is a risk to the king's life, or of war among kings.
Simple meaning: Lightning, a meteor or a thunderbolt at sunrise or sunset can point to danger for a king, or war.

A long halo round the Sun and Moon, with a red look at rising and setting, can bring a new king.
उदयास्तमये भानुराच्छिन्नः शस्त्रसन्निभैः ।
