Raja Yoga is the royal path of yoga, emphasizing meditation, mental control, and spiritual enlightenment. It focuses on stilling the mind through practices like meditation, concentration, and breath control (pranayama), aiming to achieve self-realization by experiencing the true nature of consciousness. Raja Yoga incorporates ethical principles, physical postures (asanas), and systematic techniques for mental clarity and inner peace, as outlined in the Yoga Sutras of Patanjali.
