Yogacharya B.K.S. Iyengar with his intellectual and spiritual practices has masterminded the techniques which can be used by all practitioners of yoga. "Research based experience" and "experience based research" has helped him in evolving this form of Hatha Yoga which is now known as"Iyengar Yoga".
It focuses on the structural alignment of the physical body through the development of asanas to bring inner alignment. Through the practice of a system of asanas, it aims to unite the body, mind and spirit for health and well-being. This discipline is considered a powerful tool to relieve the stresses of modern-day life which in turn can help promote total physical and spiritual well-being.
It can be said that Iyengar differs from the other styles of yoga by three key elements: technique, sequence and timing.
- Technique refers to the precision of the body alignment and the performance of pranayama.
- Sequence means the sequences in which asanas and breathing exercises are practiced. Following the specific sequence is important in achieving the desired result, because the combination of certain poses and breathing techniques can ensure the expected positive effect.
- Timing is the third key element which defines the time spent in each pose or pranayama.
Iyengar Yoga is characterized by great attention to detail and precise focus on body alignment. Iyengar pioneered the use of "props" such as cushions, benches, blocks, straps and sand bags, which function as aids allowing beginners to experience asanas more easily and fully than might otherwise be possible without several years of practice. Props also allow elderly, injured, tired or ill students to enjoy the benefits of many asanas via fully "supported" methods requiring less muscular effort.
Unlike more experiential approaches where students are encouraged to independently "find their way" to the asanas by imitating the teacher, an Iyengar Yoga class is highly verbal and precise, with misalignments and errors actively corrected. After practicing consistently for a minimum of 3 years, Iyengar teachers complete another 2 years of rigorous training for the Introductory certificate. They may complete subsequent intermediate levels and senior levels of certification, potentially entailing a decade or more of training.
