This poor young woman has spent several years earning one of the highest GPAs in her class, and at this moment captured on film she believes that she has spent that time committing the grave sin of "worshiping the intellectual mind:"
She then asserts that there are people in the audience who have not lived as Jesus has called them to live, prays that they will come to see the error of their ways, breaks into tears, starts shaking uncontrollably, and finally collapses. The video ends with one of the officers of the school asking someone to call an ambulance, and announcing the processional.
The note on the YouTube page says this occurred at Midwestern State University, Texas, and the video was posted to YouTube on January 26, 2010; but there is no other indication of when it occurred.
It is unclear from the video whether the girl in question was the salutatorian or the valedictorian. She's giving a "benediction."
Who messed with her mind so much? It seems a cruel and heartless thing to do, to rob this girl of her achievement and wind her up so much she collapses in public.
