Pranayama
Yoga sutras of Patanjali define pranayama as " The regulation of breath or the control of prana, which in essence is, the stoppage of inhalation and exhalation, which follows after securing that steadiness of posture or seat."
Regulating the breath controls thoughts of the mind. The texts say that prana is the energy in the body. Thus with the regulation of breath, the inner vital force or prana is controlled. This helps to control the mind. Pranayama helps the mind to clear itself of all negative thought patterns and renders it capable of attaining peace.
