There are 180 Iyengar Yoga Institutes worldwide. B.K.S Iyengar has evolved precise posture (asana) and breathing (pranayama) techniques with a firm philosophical base in the Yoga Sutras of Patanjali

Iyengar yoga is characterised by precision and alignment in the execution of the postures (asanas), sequencing of the asanas towards a desired result, timing in the length of time the asanas are held for maximum benefit, and the use of props if required to help a student gain the maximum benefit from each asana.

Iyengar Yoga concentrates on postural alignment and body awareness. This is not just for the alignment of one body part with another, but also for the proper functioning of the human being. If the body is aligned with precision then the breath is aligned with the same precision. If the breath is balanced then the mind, emotions and senses become balanced.
