i enjoy the idea (or at least my interpretation of it) and practice of noticing heideggers hammer. you're in the garden say, planting a plant. The hands are moving by themselves. Your knees are subtly adjusting themselves, beyond my noticing of it, to get more comfortable. My heart is doing its job of beating. The eyelids close and open without choice to do so. thought arrives and disappears without a thinker. A chill wind might come, and my body feels it by itself, i don't have to conciously choose to feel the cold. I instinctively whipe some snot from my nose. but my focus, is on the object - getting the plant in the hole. the sphere of view is the plant, it is what "I" can see, and to me in that moment it is all that exists. But all that i have described, the whiping of the nose, the thoughts that come and go, etc is happening by itself, a causeless happening. This is very beautiful to experience. i love it. it's happening all by itself, as one thing. how stupid i then feel for taking me and teh world seriously. That to me is being. An arrival, whether it is my focus or not, including my own subjectivity. This has implications for death the perception of death. No one will get to the bottom of what those implications are but there's a phemonelogical experience of being Being.
