We often talk about yoga as a 'mind/body' exercise, or about the practice of 'mindfulness', as though it was a simple dichotomy: Here is a mind and here is a body and I will put them together and be mindful. I think this is all very interesting, but a lot more nuanced and complex in practice. I've been teaching introductory mindfulness techniques in daily life for a while, and my sense is that it is helpful to have a theoretical framework in place that captures some of this nuance.
How much time do you spend thinking reasons why you "can't" do something? Why you can't lose weight, why you can't get the job you want, why you can't buy the house or car you want...etc.What if, instead, you asked yourself "How can I?" When you tell yourself you can't, you shut yourself off from any possibility of doing what you want and destroy any motivation to act. When you ask yourself, "How can I?" you open up your mind to think of possible solutions and you are motivated to act.
Yoga studios tend to have a certain look. Part of this has to do with the practical needs of doing yoga. For example, a carpeted floor tends to hold more dust, and is less desireable for a practice where your face is regularly close to the floor. Part has to do with the rather long and highly fluid history of the practice of yoga.
When you come into a yoga class it is very typical to spend some time sitting quietly. I will often explain to my students that this time is not some sort of 'before', but is a part of the class. In any 'mind/body' modality it is important to foster the conditions where the connections of the stream of thought and the stream of movement can become seamless.
