If one analyzes Channa's prayer we see that it emphasizes that life isfull of changing fortunes. Peninahad many children. But now she has 7 children that were born and witheach baby that was born, Penina lost another child. G-d makes some people poor and he makes some people rich. He makes thehaughty low and the humble high.
Fortunes keep changing.
One reads of people and institutions thatwere riding high and finds that their fortunes have turned. Fortunes are so fragile. Emotionally, Rosh Hashanna is the most difficult day of the year to keep. We can deal with Yom Kippur. We don't eat.
