Take hold of your own life. See that the whole existence is celebrating. These trees are not serious, these birds are not serious. The rivers and the oceans are wild, and everywhere there is fun, everywhere there is joy and delight. Watch existence, listen to the existence and become part of it.
We too often let the material things serve as indicators that we're doing well, even though something inside us tells us that were not doing our best. That we are avoiding that which is hard, but also necessary. That we are shrinking from rather than rising to the challenges of the age.
