'Flow' refers to the book of the same name by Mihaly Csikszentmihalyi, which describes a state of mind where our thoughts allow us to act and make decisions that are effortless and without doubt. As our body and mind become one, we 'flow'.
A wolf embodies 'flow'. Natural instincts guide it beyond hesitation and confusion. I've always believed that when we are fully immersed in our writing, we flow like the wolf. Every fiber of our being contributes to the message we are about to deliver, both in form and content.
And yes, interestingly enough, flow is wolf spelled backwards.
