This is a dharma talk on. It's one of the eight noble truths, usually translated as concentration. I will to talk about the different approaches/interpretations of Samadhi you'll find in Rinzai practice and Soto practice. I will then discuss how we might talk about Samadhi from an Ordinary Mind Zen point of view, based on the teachings of Joko Beck and Barry Magid. We emphasise no-gain and you can’t get it right or wrong right. Just sitting expresses the unity of practice/enlightenment – let go of all gaining ideas – just sit – this is it.
