“We know nothing until we know everything” is a line from a poem by 14th century Christian mystic St. Catherine of Sienna. When we realize this all questions go away and you know deeply what ‘this’ is all about. It is possible to approach this realization directly by looking deeply into our mind stream through the sitting practice of shikantaza. Give into the fundamental nature in front of you by looking at how you want something else.
