Flow is the mental state of operation in which a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. Proposed by Mihály Csíkszentmihályi, the positive psychology concept has been widely referenced across a variety of fields.

Flow (psychology) - Wikipedia, the free encyclopedia

Traditionally, the problem of existence has been most directly confronted
through religion, and an increasing number of the disillusioned are turning
back to it, choosing either one of the standard creeds or a more esoteric
Eastern variety. But religions are only temporarily successful attempts to
cope with the lack of meaning in life; they are not permanent answers. At
some moments in history, they have explained convincingly what was
wrong with human existence and have given credible answers.

The evidence that none of these solutions is any longer very effective is
irrefutable. In the heyday of its material splendor, our society is suffering
from an astonishing variety of strange ills. The profits made from the
widespread dependence on illicit drugs are enriching murderers and terrorists.
It seems possible that in the near future we shall be ruled by an oligarchy
of former drug dealers, who are rapidly gaining wealth and power
at the expense of law-abiding citizens. And in our sexual lives, by shedding

viruses upon one another.

has been used extensively to improve the quality of life. One of the most
ancient and perhaps the most popular functions of music is to focus the
listeners’ attention on patterns appropriate to a desired mood ...





THE FLOW OF THOUGHT
THE GOOD THINGS IN LIFE do not come only through the senses. Some of
the most exhilarating experiences we undergo are generated inside the
mind, triggered by information that challenges our ability to think, rather
than from the use of sensory skills. As Sir Francis Bacon noted almost four
hundred years ago, wonder—which is the seed of knowledge—is the reflection
of the purest form of pleasure.

Just as there are flow activities corresponding
to every physical potential of the body, every mental operation
is able to provide its own particular form of enjoyment.



DISORDER IN CONSCIOUSNESS: PSYCHIC ENTROPY
One of the main forces that affects consciousness adversely is psychic disorder—
that is, information that conflicts with existing intentions, or distracts
us from carrying them out. We give this condition many names, depending
on how we experience it: pain, fear, rage, anxiety, or jealousy. All these
varieties of disorder force attention to be diverted to undesirable objects,
leaving us no longer free to use it according to our preferences. Psychic
energy becomes unwieldy and ineffective.
