Signs of Twilight Hours (sandhyā-lakṣaṇa) - Verse 30

If birds, the she-jackal and other animals should howl turning to the Sun, if the twilight sky should be marked by dust and by the appearances, Daṇḍa and Parigha , and the sun should appear for several days of altered appearance, the chief ruler will die and there will be famine in the land.
