Do you know what yoga is? 

If you’re only a beginner in this practice, you may be in a sort of fortunate situation, because for you, yoga is clear as a day. You probably started classes with some teacher, and as you keep practicing, you imagine that yoga is a well-rounded practice that combines physical exercises, some breathing exercises, and relaxation techniques. The physical exercises may be more static (asanas), or more dynamic (sequences of asanas and vinyasas) and sometimes contain kriyas - a combination of breath and physical movement practiced repetitively.
