Yoga and math

I think I may be getting why it is so hard to explain yoga. Usually, we are involved in a process of addition - getting a new thing, taking a course, buying a book. We collect experiences too - going to warm climates, eating great food. These experiences "add" to our lives. But yoga is really a process of subtraction. Yoga practice has the tendency to "remove". Yoga removes stress, removes the disconnection between deeper parts of ourselves, removes some of the need for external validation. It removes muscular imbalance, and internal toxins. Meditation can remove thoughts. So, it's tough to introduce a subtraction way of thinking to an addition based culture as a "positive" benefit. Yup.
