“Cavern Lake” flows as a solemn prayer for world peace and a heartfelt plea against nuclear weapons. This short art film, directed and performed by Mariko Endo, is captured through the lens of Fred Hatt, with a haunting score composed by Dary John Mizelle. The sacred text of Mata Amritanandamayi Devi, graciously permitted by the M.A. Center, weaves through the film’s quiet power.
