IYENGAR YOGA PROPS
What are the props (support material)?
BKS Iyengar is known to have introduced the use of accessories into yoga practice. The use of this material is stimulated to enable a better alignment of the body and to enable any person to practice yoga safely and efficiently, no matter her or his physical condition or flexibility. Props can also be a good tool in teaching specific actions at each asana.
Action is movement with intelligence
