Geshe-la is showing actual data slides with graphs from his papers. For example showing that comparing mindfulness training versus compassion training, mindfulness training reduced reactivity of both positive and negative emotion to negative images, while compassion training increased negative emotion reaction slightly. And yet mindfulness did not decrease clinical depression scores nearly as much as compassion. I highly recommend Lobsang Tenzin Negi’s papers, I will have to go back and re read them myself now.
