"Behind all this, some great happiness is hiding."   ~ Yehuda Amichai
Israeli poet, Yehuda Amichai was born in Wurzburg, Germany, in 1924.  His family fled Germany for Palestine  in 1936,just ahead of the Nazis. He later became a naturalized Israeli citizen. He served in the Jewish Brigade of the British Army in World War II and fought with the Israeli defense forces in the 1948 Arab-Israeli war (from Wikipedia.)    I suspect that Yehuda experienced days in his life when it was difficult to see any happiness - days when he "couldn't see the forest for the trees."  And yet he tells us that beyond all of the sorrows and trials, there is, not only happiness, but great happiness.  We just have to look for it.
