Self-deception, a major barrier to organizational transformation, stems from the incongruence between words and deeds and the neglect of self-awareness—a phenomenon that biases managers' realistic appraisal of their abilities. Despite extensive theoretical and quantitative research, an operational model for overcoming self-deception rooted in Persian classical literature remains absent. Adopting an interdisciplinary approach and thematic analysis, this study extracts such a framework from the 79 verses of Parvin E'tesami's poem "Speech and Action"—her longest allegorical debate featuring the Lion and the Cat, offering a rich ground for analysis. Inductive coding via MAXQDA 2020 generated 247 initial codes, refined into 12 sub-themes and ultimately 5 main themes: Clear Vision, Integration of Speech and Action, Wise Leadership, Scope of Self-Awareness, and Strategic Learning. The Persian initials of these themes form "Chiregi" (Overcoming), signifying overcoming self-deception and attaining self-awareness. The novelty emerges at three levels: theoretical (bridging classical literature and management), methodological, and practical (an indigenous model). The main achievement is the Chiregi Model with five concrete components, teaching managers to formulate a realistic vision, align words and deeds, institutionalize wise leadership, cultivate self-awareness, and learn from past experiences through strategic learning. Its managerial implication lies in narrowing the claim-performance gap, restoring organizational trust, and paving the way for authentic, sustainable transformation. This research reframes ancient texts not merely as cultural heritage but as a treasure trove of behavioral patterns and managerial values, demonstrating that E'tesami's allegorical teachings, transcending their time, guide managers toward self-awareness, authenticity, and practical integrity.
