where did this too shall pass come from
This too shall pass The fable retold by Fitzgerald can be traced to the first half of the 19th century, appearing in American papers by at least as early as 1839.[3] It usually involved a nameless "Eastern monarch". Its origin has been traced to the works of Persian Sufi poets, such as Sanai and Attar of Nishapur.[3] Attar records the fable of a powerful king who asks assembled wise men to create a ring that will make him happy when he is sad. After deliberation the sages hand him a simple ring with the words "This too will pass" etched on it, which has the desired effect to make him happy when he is sad. It also, however, became a curse for whenever he is happy.[3]
Devil's Pass Director Renny Harlin spent time in Moscow researching the government archives. His own theory of what happened at the Dyatlov Pass incident is that a government experiment went wrong. The casting for the film was intentionally kept to unknowns. Shooting took place in northern Russia, and each scene was rehearsed extensively.[4]
