This personal memoir examines the philosophical and spiritual influence of Professor Abraham Joshua Heschel on a Japanese doctoral student through direct observation and study from 1970 to 1972. The author employs autobiographical narrative methodology to document his intellectual journey from studying philosophy in Japan, through encounters with Martin Buber and Gershom Scholem in Israel, to his eventual mentorship under Heschel at the Jewish Theological Seminary. The study reveals Heschel's distinctive approach to reconciling critical scholarship with religious faith, particularly his ability to maintain biblical vitality while engaging in rigorous textual analysis. Through detailed accounts of personal conversations, walks, and philosophical discussions conducted in Hebrew, the research illuminates Heschel's integration of social activism with theological conviction, demonstrating how his political positions on issues including the Vietnam War and civil rights emerged from biblical and Torah-based foundations rather than secular liberalism. The findings indicate that Heschel's pedagogical method emphasized prophetic tradition, combining intellectual rigor with compassionate engagement with contemporary social issues. The author concludes that Heschel embodied a unique synthesis of scholarly excellence and spiritual authenticity, representing what he terms "divine compassion" manifested through persistent advocacy for peace, justice, and redemption in both academic and public spheres.
