When I first stepped onto a yoga mat I wasn't sure what I was stepping into. It's kind of like when you meet someone who changes your world. One day you are living your life and all is good then you see them, you meet them, you chat, and your life doesn't drastically change but from that moment they are always somewhere in your mind, in your heart. At the back of your breath you can feel their presence and there is an air of support and strength that maybe wasn't there before. Or maybe it was but now you can taste it. That's how I feel about Yoga.
