"Playing in earnest" is creating meaning rather than "uncovering" it
Life is empty and meaningless. From a Western point of view, because life is meaningless, we suffer (nihilism). We are preoccupied with meaning, with somethingness. Our metafysics and spirituality is profoundly geared toward meaning. Observe, for example, how the dense cultural mass of christianity pulls everything in orbit around it. Christ is destined to die on the cross for our sins. Here, meaning is derived from weight (destiny) and purpose (sacrfice). See how easily this translates into relationships: are we meant for one another (destiny)? Does suffering give meaning to our relation (sacrifice)? In fact, does suffering give meaning to our lives?
