According to the late Wilmot P Wijetunga
Of Visitors. If a crow makes a guttural sound in front of the house, visitors will shortly arrive.
Of Death. The weird cry of the devil-bird portends that death will visit the house over which it flew while making the cry.
Black Ants. Long lines of these infesting a house are believed to be an ill-omen. 'Bali' ceremonies are resorted to drive them away and to counteract the future disasters which they indicate.
Cobras. The average Sinhalese seldom or never kills a cobra that might choose to make its home in his dwelling.
Eating. The best position in taking meals is facing the East which brings good luck. Facing West is also good, but he other two points of the compass are to be avoided.
Bathing. Bathing on the different days of the week is said to have the following effects on the bather:- Bathing on Sunday - spoils the bather's appearance; on Monday - improves it; Tuesday - brings on disease; Wednesday - brings riches; Thursday - creates quarrels; Friday - his children die; Saturday - brings happiness and deemed the most suitable day for bathing.
