The state of flow, also known as being "in the zone," is a mental state in which a person is fully immersed and focused on a task, feeling a sense of energized focus, full involvement, and enjoyment in the process of the activity. This state was first described by psychologist
Mihaly Csikszentmihalyi, who found that people who experience flow report feeling a sense of timelessness, clarity of purpose, and heightened creativity and productivity.
During a flow state, people often lose self-consciousness and become completely absorbed in what they are doing, often leading to a feeling of being "in the moment" or "present." Flow can occur during a wide range of activities, including sports, creative pursuits, work, and leisure activities.
To achieve a state of flow, the task should be challenging enough to require full attention and engagement but not so difficult as to cause frustration or anxiety. The individual should have a clear mind, receive immediate feedback on their performance, and have a sense of control over the situation.
It is very come in a Systema class to hear the instructor saying 'Keep moving', 'Stop thinking', 'Let yourself go', 'don't be tense' and of course 'Breath'.
