Systems of belief are the tracks that knowledge leaves behind. Questioning and open inquiry offer far more - Tarthang Tulku. Throughout human history, there have been attempts to capture knowledge in the form of labels and specific belief systems. This does not do justice to knowledge, for systems of belief are the tracks that knowledge leaves behind. Questioning and deepening inquiry offer a far more immediate approach. Starting with the simple fact of our presence in the world, Sacred Dimensions of Time and Space crafts a "geometry of meaningful existence". The result is utterly unexpected and deeply liberating- a new architecture of experience. The reader can join in an inquiry that leads to personal transformation. Twenty pages of diagrams present visual metaphors for new ways of thinking about space, time, knowledge, and the arising of experience. This is the fourth volume in the Time, Space, and Knowledge series but can be read independently.
