Various schools or styles of Yoga have grown around each of these paths, which emphasise different aspects of these paths, or a combination of them, in their practical methodology. Usually these schools are established by renowned teachers or gurus and reflect their methodologies and ways of practicing, teaching and following the path of yoga. Some of the most well known modern schools or styles of yoga include: Iyengar, Astanga, Vini, Ananda, Anusara, Bikram, Integral, Kali Ray Tri, Kripalu, Kundalini and Sivananda. (See this article for a brief explanation of the differences between some of these schools at a practical level in terms of how classes are run.) Interestingly, three of the most popular schools today – Iyengar, Astanga and Vini Yoga – were all developed by students of Sri T. Krishnamacharya.
Particular styles or methods may be considered more effective than others or may suit an individual’s temperament better. That said, it must always be remembered that all these are merely different methods of reaching for the same ultimate goal. They are all aspects of the overall philosophy of Yoga.
