Naad is a Sanskrit term that refers to the primal sound or cosmic vibration that underlies and sustains the universe. In yogic and spiritual traditions, Naad is considered the essence of all sound and the source of all creation. It is believed that by attuning to this subtle vibration through practices such as chanting, mantra, and meditation, one can harmonize with the universal energy, leading to spiritual awakening and inner peace. Naad Yoga, the yoga of sound, focuses on using these vibrations to elevate consciousness and connect with the divine.
