I have long been interested in trying to find out how people experience, or sense, their own existence—for what specific sensations do they use the word 'I'? Few people seem to use the word for their whole physical organism. 'I have a body' is more common than 'I am a body.' We speak of 'my' legs as we speak of 'my' clothes, and 'I' seems to remain intact even if the legs are amputated. We say, 'I speak, I walk, I think, and (even) I breathe.' But we do not say, 'I shape my bones, I grow my nails, and I circulate my blood.' We seem to use 'I' for something in the body but not really of the body, for much of what goes on in the body seems to happen to 'I' in the same way as external events. 'I' is used as the center of voluntary behavior and conscious attention, but not consistently. Breathing is only partially voluntary, and we say 'I was sick' or 'I dreamed' or 'I fell asleep' as if the verbs were not passive but active. Nevertheless, 'I' usually refers to a center in the body, but different peoples feel it in different places. For some cultures, it is in the region of the solar plexus. The Chinese hsin, the heart-mind or soul, is found in the center of the chest. But most Westerners locate the ego in the head, from which center the rest of us dangles. The ego is somewhere behind the eyes and between the ears.
