In Iyengar Yoga classes students learn discipline, learn to pay attention to one’s actions, learn to see the results of one’s actions, learn discrimination, and this leads to the ability to practice to heal and overcome one’s afflictions and prevent future pains. Alignment within the poses, alignment of the sequences, the way the class is set up, the way we use props, instructions, etc, everything is done purposely to help the students transform and develop skills ultimately to experience “yoga.”
There are poses I saw Guruji BKS Iyengar practicing in Pune that I am still trying attempting to approach.
