Any and all of the questions you pose to your mind regarding its nature do not yield answers. There are no answers. The questions themselves dissolve. There is nothing to seek and find, nothing to grasp, there ius nothing solid at all. Everything opens to the boundless state. This is the true nature; in Buddhism is called emptiness. (p55)
If you think it’s frustrating to try learning Dzogchen, you should try teaching it… there’s nothing sensible to say. We try to be helpful, but we haven’t got anything. Just “Hey, wow, LOOK AT THAT!”
