Psychoanalyst and Zen teacher Barry Magid writes in his essay titled Uselessness in the Fall 2013 issue of Tricycle magazine:

When we speak of just sitting, we are not limiting ourselves to describing a particular posture or practice. We are describing a way of being in the world in which everything we encounter is fully and completely itself. Nothing is merely a means to an end, nothing is merely a step on the path to somewhere else. Every moment, everything, is absolutely foundational in its own right.
