Still, smoky shapes like an umbrella, a banner or a flag may sit in the Sun's disc, with sparks. They may bring harm to the world.
Simple meaning: Smoky umbrella or flag shapes with sparks on the Sun's disc can bring harm to the world.
सितरक्तैः पीतकृष्णैर्वर्णैर्विप्रादिपीडनम् ।
Coloured marks on the Sun may trouble the four classes. Many-coloured marks can put royal lives at risk.
ऊर्द्धैर्भानुकरैस्ताम्रैर्नाशं याति चमूपतिः ।
Copper, yellow, white or many-coloured upward Sun rays point to risk for the army chief, prince, priest or people.
धूम्रैर्नृपपिशंगैस्तु जलदाधोमुखैर्जगत् ।
Smoky rays may harm the king, downward rays the world. Tawny rays bring rain. A copper late-winter Sun is good.
