Within the eight-limbed discipline of Rāja Yoga, concentration is articulated as dhāraṇā, the sixth limb, and marks a decisive turning toward the inner life of the mind. After the groundwork of ethical restraints and observances, posture, breath regulation, and withdrawal of the senses has steadied and purified the practitioner, dhāraṇā gathers the mental energies into a single, deliberate focus. This focus may rest on a chosen object, thought, or point of awareness, and the essential feature is the intentional holding of attention without allowing it to scatter. Through this sustained effort, the restless and distracted tendencies of the mind are gradually weakened, and a more stable, one-pointed awareness begins to emerge.

Dhāraṇā thus serves as a bridge between the preparatory limbs and the higher states of consciousness that follow. When concentration becomes steady and relatively unbroken, it matures into dhyāna, where awareness flows continuously toward its object. As this deepening continues, the process culminates in samādhi, in which meditative absorption becomes so complete that the distinction between subject, process of knowing, and object is progressively effaced. In this way, concentration is not merely one practice among others, but the functional prerequisite for genuine meditation and for the possibility of full meditative absorption.

Because of this pivotal role, dhāraṇā may be seen as the mechanism by which the mind is transformed from a scattered instrument into one capable of direct spiritual realization. By repeatedly returning attention to a single chosen point—whether a mantra, a symbol, the breath, or another suitable focus—the practitioner cultivates inner steadiness and clarity. Over time, this collectedness of mind supports the unveiling and refinement of deeper patterns within consciousness, making them available to insight and further purification. In Rāja Yoga, concentration therefore stands as the crucial turning point where disciplined preparation ripens into the contemplative absorption that leads toward liberation.
