Some say that anahata nada, or the sound of silence, is perfection. According to yogic teachings, this sound is necessary for all other sound to exist because it is the canvas upon which other sounds are manifest.
In yoga, it is taught that the sound of anahata nada can be represented as Aum or Om, the sacred syllable and revered bija mantra. This is the sound from which the whole universe emanated and represents the fundamental oneness of all creation.
In Kundalini yoga, it is said that the goddess of kundalini shakti embodies anahata nada. She is portrayed as a serene goddess, centered on her selfless spiritual devotion. Her energy, and that of anahata nada, is upward moving.
