Psychology of 'flow'

This is such a wonderful topic for a lengthy discussion that SE does not support with its restrictive Q&A format. So now one has to perform the herculean attempt to frame an answer that might capture at least some of that broad discussion.

Your note on homestasis resonates deeply with the following from MN121

There is only this that is not emptiness, namely that associated with the six sense fields dependent on this body and conditioned by life.

In fact all of MN121 explores, if you would, the homestatic evolution of emptiness that culminates with this invitation to Ananda:

So, Ānanda, you should train like this: ‘We will enter and remain in the pure, ultimate, supreme emptiness.’

Note that this invitation was extended late in life.

"Ānanda, these days I usually practice the meditation on emptiness."

I trust I properly heard, learned, attended, and remembered that from the Buddha?

Before that came the entire Noble Eight-fold Path with all of the practice detailed in other suttas. But that's a topic for a different day.

"Go with the flow" is the practice of animals and lazy slaves... and all they are willing to scarifies: nothing, but wishing to eat.

Many years ago Bhante Thanissaro wrote an approach to the "go with the flow" and the value of the Dhamma on the other side.

The Karma of Happiness: A Buddhist Monk Looks at Positive Psychology

“This is the way leading to wisdom: when visiting an awakened person, to ask … ‘What, when I do it, will be for my long-term welfare and happiness?’”...

... if psychologists could remain open to the possibility that there’s an unadulterated happiness that doesn’t fit into their framework of a full or meaningful life, it would serve as a sign that they had become genuinely wise.

This sounds like the application of the practice of mindfulness in daily life.

For example, from "Chapter Six: Daily Life" of Yuttadhammo Bhikkhu's book "How To Meditate":

When cooking, cleaning, exercising, showering, changing clothes, even on the toilet, one can be mindful of the movements of the body involved, creating clear awareness of reality at all times. This is the first method by which one can and should incorporate the meditation practice directly into ordinary life.

From the teachings of Zen master Thich Nhat Hanh, we find the use of mindfulness in daily life for example:

In the kitchen:

The kitchen is also a meditative practice space. Let us be mindful when we are cooking or cleaning in this space. Let us do our task in a relaxed and serene way, following our breathing and keeping our concentration on the work. A few words only may be needed about the work at hand. We might like to start our work by offering incense to the kitchen altar, to express our gratitude and to remind ourselves to work mindfully.

Let us support the kitchen teams by not disturbing this meditative space unnecessarily. We do what we have to in silence and leave the kitchen so the teams can do their work.

While cooking, we allow enough time so we will not feel rushed. Let us be aware that our brothers and sisters depend on this food for their practice. This awareness will guide us to cook healthy food infused with our love and mindfulness.

When we are cleaning the kitchen or washing our dishes, we do it as if we are cleaning the altar or washing the baby Buddha. Washing in this way, we feel joy and peace radiate within and around us.

Drinking tea (tea meditation):

Tea meditation is a time to be with the Sangha in a joyful and serene atmosphere. Just to enjoy our tea together is enough. It is like a “good news” occasion, when we share our joy and happiness in being together.

At times, when we are drinking tea with a friend, we are not aware of the tea or even of our friend sitting there. Practicing tea meditation is to be truly present with our tea and our friends. We recognize that we can dwell happily in the present moment despite all of our sorrows and worries. We sit there relaxed without having to say anything. If we like, we may also share a song, a story or a dance.

Eating together:

We should take our time as we eat, chewing each mouthful at least 30 times, until the food becomes liquefied. This aids the digestive process. Let us enjoy every morsel of our food and the presence of the dharma brothers and sisters around us. Let us establish ourselves in the present moment, eating in such a way that solidity, joy and peace be possible during the time of eating.

Eating in silence, the food becomes real with our mindfulness and we are fully aware of its nourishment. In order to deepen our practice of mindful eating and support the peaceful atmosphere, we remain seated during this silent period. After twenty minutes of silent eating, two sounds of the bell will be invited. We may then start a mindful conversation with our friend or begin to get up from the table.

Upon finishing our meal, we take a few moments to notice that we have finished, our bowl is now empty and our hunger is satisfied. Gratitude fills us as we realize how fortunate we are to have had this nourishing food to eat, supporting us on the path of love and understanding.

Service meditation:

To participate in service meditation can be a great happiness. It is an opportunity to engage in the maintenance and care of our practice center while enjoying our practice of mindfulness. When we wash the cars, or turn the compost piles or chop wood we stay mindful of our breathing and the activity that we are doing. We speak only when necessary and about the work at hand. We can maintain a light and easy feeling as we work. An environment that is quiet can make the work more pleasant and enjoyable. When we work in the garden we get in touch with the plants and nourish our connection to the earth we are living on. Sweeping and mopping the meditation halls we see that we are already practicing to calm our mind and body. Please, do not be in too great of a hurry to get the job done. Our most important contribution to the Sangha is to maintain our practice of mindfulness.

Service Meditation links us to our everyday life, both here and when we return home. As we are working at our computer or preparing dinner for our family or teaching a class, we can practice stopping, calming and refreshing ourselves with our conscious breathing. We can relax and smile at our co-workers and pace ourselves to maintain a light and serene state of being.

Most of the human actions/habits are to suppress their suffering or cover it up. The ordinary human mind's direction is avoiding certain thoughts, feelings and emotions and to do that developing certain habits, addictions. Playing games, studying the lessons, watching television, listening to music, sensuality, following the politics, watching football, talking with others etc.. Some of the human actions leads a person to a kind of "trance state" but I think that is generally not high awareness but it leads people to kind of a unconscious state that can bring him/her temporary calm. I am not sure the "hyperfocus" that is mentioned in the article is always meditative hyperfocus. In some activites like playing games, using the technology, reading a book, studying the lessons etc. it can be the opposite(because the person is not having clear awareness) unless there is some real mindfulness involves in the "focusing".

In Buddhism, meditation and mindfulness this is useful and beneficial. Absorbing in what you do in the present moment mindfully is creating a "flow" that carry you to peace, happiness and freedom from suffering. The other answers are very good so there is not so much for me to add to this subject.

Great question. Thank you.
