The structure of thought, the convoluted geography of our personalities, the world of ideas is complex and subtle. If we put ourselves in the position of thinking about the way we think, we have a tricky situation to say the least. We are obviously limited in our thinking, by our style of thinking. So; something apart from thinking needs to look at thinking. But what could this be? Buddhism describes this ‘something’ as the open dimension of being. It is the discovery of space.
