To properly teach yourself yoga, all students will require some form of external assistance, in addition to traditional learning materials. To succeed in yoga, you will need a deep understanding of many other subjects that will be foundational to almost all of general yoga. Every yoga course builds upon the foundational concepts from previous classes, from physical science to math for analytical yoga. Without some guidance, or having a tutor connect the ideas for a student, it can become unnecessarily difficult to be self-taught.
