This chapter presents the teachings of a Hasidic teacher, Menahem Nahum of Chernobyl. The chapter focuses attention on the notion of da'at, knowledge or consciousness, as it appears in Rabbi Menahem Nahum's classic Me'or einayim. The chapter considers it the ultimate goal of the mystical life. Focusing on da'at provides a particular approach to the issue of religious truth. In the chapter, religious truth is viewed from the subjective and cognitive dimension, in terms of human consciousness and its ability to enter the reality of God. It explores the relationship between this cognitive and the conscious dimension of approach to God and the more objective dimensions of religion in relation to the notion of truth. The chapter offers a turn to the subjective, the experiential, and the conscious as a means of safeguarding the foundations of truth, grounded in God, and the quest for da'at. One might almost discern a parallel between the appeal to da'at on metaphysical, cognitive, and mystical grounds and Krajewski's appeal to a kernel of historical truth in tradition. However, da'at is more than a kernel. In fact, da'at is the essence, the goal, and what counts most in the spiritual quest. Getting to the heart of things, therefore, allows us to rebalance perspective and to affirm that which matters most in religion, its ultimate truth, despite the weakening of the historical and other foundations of the religious system.
