The Buddha talks about penetrating the objects of observation; diving into them and observing the body in the body, the perception in the perception; only so we can know the object. From observation comes insight; from insight comes knowledge. In the end it is deep observation that leads us to an interaction based on understanding. The interaction closes the loop; an interaction based on insight or true understanding creates meaning.
“When you practice deep looking and master yourself, you dwell in peace freedom and safety.”~Thich Nhat Hanh
