Rabbi Shimon ben Gamliel, quoting Rabbi Yehoshua, said something that should stop us: since the destruction of the Temple, not a single day has passed without a curse (Sotah 48a).
He did not mean plagues and catastrophes, though there were those too. He meant something quieter and more intimate. The dew no longer falls with a blessing. The fruits have lost their proper taste. An apple is still an apple, and a fig is still a fig, but the sweetness that tongues once knew in Jerusalem has been dialed down. Creation has gone a shade dimmer.
Rabbi Yossi added to the list: "Also the lusciousness of the fruit is gone." Rabbi Shimon ben Elazar stretched it further: "With the decay of purity, the taste and aroma of the fruit disappeared, and so did the richness of the grain and the blessing in the tithes."
The sages, summing up the decline, said simply: "Zenut u-khshafim — lewdness and witchcraft ruin everything."
The ruin of the Beit HaMikdash in 70 CE was not just a political event or the loss of a building. In the rabbinic imagination it cracked the world at the level of taste buds and rainfall. The Temple was a tuning fork for creation, and when it fell, everything went slightly flat.
The rabbis teach this not to make us mourn forever, but to remind us that the taste we have right now — imperfect, diminished — is still good. And that one day the whole world will be sweetened again.
