Abstract: Yoga is frequently viewed through the lens of physical fitness, yet it is fundamentally grounded in a philosophy of self-realization and internal transformation. Recent contemporary interpretations, notably "Inner Engineering" by Sadhguru, have reframed yoga as a sophisticated tool for recalibrating the internal dimensions of the human experience. This paper investigates the conceptualization of yoga as "inner engineering"—a systematic internal process aimed at optimizing the body, mind, emotions, and energies to facilitate holistic well-being. By synthesizing traditional yogic literature, empirical scientific data, and modern adaptations, this study provides a comprehensive analysis of yoga as a transformative technology for internal alignment and self-mastery. Yoga’s identity as an "internal technology" is a systematization of ancient Vedic and post-Vedic wisdom. Vedic Foundations: The roots of yoga are found in the Vedas and Upanishads, which introduced concepts of Atman (self) and Brahman (universal consciousness) as the basis for spiritual pursuits. The Eightfold Path: Patanjali’s Yoga Sutras systematized yoga into an eightfold path (Ashtanga Yoga), providing a step-by-step inner journey for self-discipline and enlightenment. Energy Mastery: Medieval traditions like Hatha and Tantra focused on mastery over internal energy systems, such as chakras and nadis, to awaken transformative forces like Kundalini.
