(Dhāraṇā): “Concentration,” the sixth limb of Patanjali’s Ashtanga Yoga. It is one of the internal stages. The word dharana comes from the root dhri, meaning “to hold.” In the Yoga Sutras (111:1), Patanjali describes concentration as “the binding of consciousness (mind) to a single place.” This “place” may be physical (a material object like a candle flame or flower), energetic (a chakra, energy center, or nadi, energy channel), or a repeated mental thought, image, sound, light, or mantra. Concentration can be inward or outward and the practice can be performed with the eyes open or closed.
