If in the Vasanta (April-May) there should occur a thunderbolt or an earthquake, or if the roar of thunder should be heard immediately before sunrise and after sunset, or if the appearance of a halo, dust-storm or smoke should be seen, or if the Sun should appear very red both at rising and setting; or if trees should yield food, juice, oil, honey, flowers or fruits, and if cows and birds should appear lustful, there would be prosperity in the land.
