“ In the forty minutes I watched the muskrat, he never saw me, smelled me, or heard me at all. When he was in full view of course I never moved except to breathe. My eyes would move, too, following his, but he never noticed. Only once, when he was feeding from the opposite bank about eight feet away did he suddenly rise upright, all alert- and then he immediately resumed foraging. But he never knew I was there.I never knew I was there, either. For that forty minutes last night I was as purely sensitive and mute as a photographic plate; I received impressions, but I did not print out captions. My own self-awareness had disappeared; it seems now almost as though, had I been wired to electrodes, my EEG would have been flat. I have done this sort of thing so often that I have lost self-consciousness about moving slowly and halting suddenly. And I have often noticed that even a few minutes of this self-forgetfulness is tremendously invigorating. I wonder if we do not waste most of our energy just by spending every waking minute saying hello to ourselves. Martin Buber quotes an old Hasid master who said, “When you walk across the field with your mind pure and holy, then from all the stones, and all growing things, and all animals, the sparks of their souls come out and cling to you, and then they are purified and become a holy fire in you. ”
