Calming down the vrittis
Yoga is the stilling of the mind's modifications. Discipline in all aspects of life is the foundation. The mind's thoughts are like waves in a pond; a single ripple obscures clarity. As long as thoughts are unpeaceful, meditation is not present. To calm the vṛttis, one must practice and seek solitude. A retreat to a peaceful natural place allows the system to recharge and quiet. The practice of Brahmari Pranayama specifically calms the brain and sharpens the senses through sound vibration. This sound connects to the primordial Om, the formless source of all creation. Everything visible and invisible arises from this sound.
"Yogaḥ citta-vṛtti-nirodhaḥ: through the practice of yoga, you can calm down all your thoughts, your vṛttis."
"Everything—all that is visible, invisible, hearing, tasting, feeling—all this is only from one source: from the Aum, the sound."
