There was no beginning to the chain of causality; it is useless to speculate how phenomenal existence started. However, it can be ended, and that is the ultimate goal of Buddhism -- the ultimate liberation of all creatures from the pain of existence. Sometimes this causality is spoken of as a circular linking of twelve different factors; if the chain of causality can be broken, existence is ended and liberation attained.

The mind senses thoughts and ideas much the same as the eye senses light or the ear senses air pressure. Thirdly, there is the factor of perception; here is the faculty which recognizes physical and mental objects. Fou...
