The flow state

We experience the "flow state" when a given task becomes effortless and time slips by without our noticing. It's an absorbing, intrinsically rewarding state that we enter when performing certain tasks.

When in the flow state we experience mindfulness and actions and awareness merge, so that it seems like the task is almost performing itself. Despite this, there's still a sense of personal control over the task at hand, and performing it feels intrinsically rewarding.
