Why do we afflict the body in order to reach the soul?

This source-based essay from The Journey to Yourself explores the question: Why do we afflict the body in order to reach the soul? It develops the theme through Torah sources and reflection on Yom Kippur, fasting, body and soul, attention, and the spiritual meaning of temporarily stepping back from ordinary physical needs. This localized discovery layer is intentionally limited to the reflective core of the Hebrew source. It does not repeat or certify historical, medical, psychological, liturgical, halakhic, or empirical details that remain under review in the full Hebrew article; it is not individualized medical, mental-health, financial, legal, or halakhic advice.
