The document discusses the practice of pranayama, which is the regulation or control of breath. Pranayama is an ancient yogic practice that aims to still the mind by controlling the breath. It provides a basic 15-step pranayama practice that begins with conscious breathing in a relaxing environment and progresses to deeper breathing by imagining filling lungs like balloons on the inhale. The practice concludes by taking three focused breaths to bring in fresh air and release toxins on the exhale. Regular pranayama practice can aid meditation.
