The Koren Ani Tefilla Siddur is one of the latest in Koren’s growing collection of siddurim (prayer books) geared towards a specific demographic. Koren describes Ani Tefilla as “an engaging and thought-provoking siddur for the inquiring high school student and thoughtful adult.” Koren says that Ani Tefillah has been developed in order “to help the user create their own meaning and connection during the Tefilla [prayer] experience.” The name of the siddur is connected with its objective. Ani Tefilla means “I pray.”
