How exactly does this transformation happen? As well see in the next chapter, there are three primary wind channels within the body. The middle channel runs down the center of the back, following the spine. On either side of it run two lesser channels.
Remember the Great Mistake: how we try to get the things we want in the wrong way, like a child hitting a bad man on a movie screen. This then plants negative seeds that ripen into our very troubled world.
When we see things in a wrong way, the inner winds inside the two side channels are active. This is because they are tied to mistaken thoughts about how our world works, and these thoughts run in the same two channels.
The incredible magic of yoga is that it actually attacks negative thoughts on a physical level, as the exercises release blockages of inner winds in the side channels.
These blockages cause us to see things in a polarized way: this and that, me and you, what I want versus what you want. When the blocks are freed, then getting what you want becomes getting what I want, and we are both freed.
