Cessation; dissolution. This term is very important, as it is present in the first part of the definition of yoga given in the Yoga Sutras: “Yogash chitta vritti nirodhah.” This means that yoga is the nirodha (cessation) of all the vrittis (movements) of chitta (the mind-field). Because the movements of the mind are quieted, we dis-identify from them and remain as the pure Witness Consciousness (the Supreme Self), or purusha, as Patanjali calls it.
