A skilled composer is commissioned to write a magical symphony for a Broadway musical. This is the biggest gig of her life. She spends many long hours notating and revising, trying this note and that, the first verse, then the next, one instrument then another. Moving on to the chorus, she repeats the process, spending long, strenuous months devoted to this project, perfecting the harmonies and virtuosic solos, weaving between the different sounds to strike perfect orchestration.
Finally, the big day arrives. The performance is live! Each note that took weeks of fine-tuning to get exactly right, smoothly played, combines seamlessly in an other-worldly melody.
Exile is the practice stage, refining physical life so that its G-dly light can shine through. Each object, every interaction, is individually defined and the focus of human effort, one at a time. Some take days, some weeks, some months, some years, even decades and centuries to reach perfection.
Then: Redemption, opening night. Each note falls into place, none skipped, but neither noticed, only part of the greater composition of sheer magnificence.
In the Messianic era, all the material elements fine-tuned over the course of history will finally express their ultimate potential. The toil and effort of the long exile will be but a memory. At that time, every material object, every physical act, will be recognized as a vehicle for expressing G-dliness. Indeed each perfect pastry, every non-factory produced garment, is vital in achieving musical harmony. Each is a background note, effortlessly contributing to the fulfillment of the cosmic symphony.
The Messianic era will be replete with extraordinary physical phenomena, like ready-to-eat food from the field. This is a reflection of the complete, transparent G-dliness that will permeate the physical world.
