The vastness of the sky may be hard to name, but only sincerity can stand the test. The spirit is abundant and as if present, and there is a sense of connection in the heart. The sky is so high that all things are blessed by rain and dew. The earth is so thick that all four lives are nurtured with grace. When frost and snow fall and wind and rain strike, it all comes down to the Tao. The four seasons move forward and all things thrive. What is there to teach?
