It was believed for awhile that this poem had been discovered in a chuch in Baltimore in 1692, however it is now known that a poet and lawyer, by the name of Max Ehrman wrote it sometime around 1927.
Ehrman lived from 1872, to 1945, in Indiana. He is said to have wanted to write a humble poem which might do good.
There was a mixup, about the origin of the poem because a pastor, found a copy of this poem sometime in the 1950 's and it was printed on a paper with the name of St. Mary's Church, Baltimore, founded in 1692.
In spite of the small mixup, I do think this poem has influenced many people in a positive way.
According to The Free Dictionary, "desiderata" is the plural of the word "desideratum", and means "the essentials of a good life", and "Something considered necessary or highly desirable".
I think it's a lovely, gentle instruction - and I never grow tired of reflecting on it.
I enjoyed this video using Desiderata - maybe you will too! :)
