Cutting a Citron in Half
Interpreters believe that whoever sees himself cutting a citron in half may be blessed with two children, a girl and a boy, who might suffer from illness. As for a woman seeing a wreath of citron tree on her head, it may indicate her marriage to a man of good reputation and religion. If she sees a citron in her lap, she may give birth to a blessed son.
