Although Yoga is the Ancient science and originate from India, but it's not mean that Yoga is India's personal property, sometime some of Yoga teachers think that their Yoga is the most standard, their Asanas are always RIGHT, and only their style is RIGHT. Who give this authentication that only their Yoga is right ? Although every teacher have their own style but Yoga is not anybody's personal property, Asana practice not to raise your Ego, but to remove ego. If practice Asanas are raising your Ego then you are on the wrong path, be careful.

   

   尽管瑜伽起源于印度，是一种古老的科学，但那并不意味着瑜伽只是印度的财产。有时一些瑜伽老师认为他们的瑜伽是最标准的，他们的体式总是对的，只有他们的风格才是对的。谁说只有他们的瑜伽才是对的？尽管每个老师都有他们自己的风格，但瑜伽不是任何人的私有财产。体式的练习不是使你变得更加自我，而是祛除这种自我。如果练习体式使你越来越自我，你就走在一条错误的道路上。小心！ Om
