What is the Buddhist interpretation of the flow state?

Rephrased question: Sometimes we become absorbed in an activity, such as writing an article, with intense focus and absorption (intentionally). How would Buddhist principles address this state? -------------------------------------- Previous question as definition of mindfulness incorrect: In being mindful we are aware of our thoughts, feelings, emotions and physical sensations Sometimes we become absorbed in an activity, such as writing an article, with intense focus and absorption (intentionally). On the surface this appears to be in conflict with mindfulness. Is this the case?
