My first epiphany that this might work came on my first day, when I went into biofeedback. They hooked me up to computers through electrodes, put me in a comfortable lounge chair, put an eye pillow over my face, slipped speakers onto my head and played an audio guided visualization.

I was at a point in my life that was really between life or death, and I sort of intuitively and instinctively knew, I have to listen.

I had never done any sort of yoga before, and this epiphany was a little more esoteric. I walked into the yoga room and there was a voice from my soul that said out loud, This is it! I just knew. I just knew in that moment - I couldn't even straighten my legs. I couldn't sit cross-legged on the floor. I couldn't put my legs up the wall in the most gentle, restorative yoga pose, and yet, I knew.

Well for me, courage means having the courage to walk off the edge of what is known, with complete faith that you're not going to go crashing to the bottom. Stepping outside of your own self-perceived boundaries and limitations.

Definitely an intelligence in the light of the heart. In yoga, we refer to this as the heart center - right behind the breastbone, and visualize it as a golden candle flame of light and spirit.

I was charging forward too hard, into too many war zones, working too long, drinking too heavily, pushing forward, pushing forward. And who knows, had this not happened, maybe I would have been one of the casualties as a journalist covering the war. Who knows, maybe I would have been captured and tortured somewhere along the line, because I always pushed things to the limit.

I feel positive when I feel vulnerable, because it's another reminder that it's not all about me and about my ego.
