Zazen is a practice of harmonizing mind and body that has been passed down for over a thousand years. It involves regulating breathing and posture, and simply sitting. What happens to our perception during this act? In this Zen session, we will explore how breathing and meditation affect perception from a cognitive science perspective. The transformation of consciousness brought about by zazen is explained as a shift in the brain's information processing mode. With this perspective in mind, you will sit with the head priest.
