Today at 97-years-old, Tao Porchon-Lynch is the world's oldest living yoga teacher, recognized by the Guinness World Records since 2012. The former actress/model is also a celebrated ballroom dancer, with a recent appearance on America's Got Talent that wowed the judges and led to a standing ovation.

I've worked with Tao every spring and autumn since she was 93. And what amazes me most is that she grows more youthful each time we meet. This is the most inspiring phenomenon I have ever witnessed.

Each time we've worked together over the years, Tao wears a different color. In honor of her birthday (August 13), here is a selection of 20 images to celebrate my favorite model/person/woman/yogi in the entire world.
