In Abraham Joshua Heschel: The Call of Transcendence (Indiana University Press, 2013), Shai Held, Co-Founder, Dean and Chair in Jewish Thought at Mechon Hadar, offers a sympathetic, yet critical, examination of the thought of this influential mid-twentieth century theologian, scholar, and activist. Held identifies a central theme that runs through all of Heschel’s writing: the idea of transcendence–the movement from self-centeredness to God-centeredness. For Heschel, prayer is the paradigmatic spiritual act, one that tries to bring God back into the world.
