“The person who taught me how to vary postures, to bend the legs, to turn the neck, all the simple and complicated variations, as necessary, is Krishnamacharya. It is important to vary each posture according to the individuals requirements.
Further, he also introduced the use of other aids or supports, so that the person gets the benefit of a posture through other means when he is not able to do the posture itself. This can involve sitting on a chair, using a roll, using supports, etc., the use of other means to help a person achieve certain results.”
– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’, given at Zinal, Switzerland 1981.
