Being ocean 1: meditation and contemplative neuroscience

  • The "Be the Ocean Watching its Own Waves" metaphor is a way to experience non-duality and a self-calming mind

  • EEG measurements during this meditation show marked changes

My idea of relaxation is being on the West Coast of the Algarve in Portugal. Quite often I just sit there and imagine that I become the ocean watching its own waves.

This is a very old meditation metaphor.

It´s calming for me, as I drop the distinction between good waves and bad waves, small or big waves, crashing of gentle waves. As everything becomes waves that arise and subside again, forever, apparently arising from nowhere.

The ocean represents the wide space of awareness in which everything occurs.

The waves refer to mental events: sensations, emotions, and thoughts. Concepts, stories, feelings, memories, anticipations. Just letting them all come and go.

How does this relate to neuroscience, meditation, and art?

Here are three perspectives on the ocean and its waves: meditation, science and art.


I have often used the ocean as a helpful metaphor for myself to go into a particular state. . The ocean metaphor/analogy facilitates the mind to switch into a particular perceptual position, vantage point, or view: the perception of being one huge spacious ocean expanse, watching its waves as itself. There is no more difference between consciousness and its events: events are an emanation of consciousness. This is one form of non-duality.

has received many inspirations from the ocean, some of them taking up deeply spiritual experiences of one-ness or loss of Self.

This post describes the meditation and the scientific perspectives on the ocean. In a second post, I will look at music, film and poetry.

1. Ocean and waves in meditation

The ocean and wave metaphor is an essential element of teaching in several Buddhist traditions such as Mahamudra and Dzog Chen. It is the standard teaching metaphor of the poet Milarepa

Why are metaphors used extensively? It is difficult for meditation teachers (actually, for anyone) to describe mystic states of one-ness, or of non-duality, to those who have not experienced them yet. So, how to guide students to those experiences/states they never had?

By their very nature, which is not like our unreflected everyday experience, such experience seems to be ineffable, inexpressible.

However, as Daniel P Brown says in "Pointing out the Great Way", this is wrong: in the West, we have not developed a precise vocabulary for the physical and mental characteristics of extraordinary states. The Tibetan meditation culture, in contrast, has built a precise language for extraordinary states.

One reason for the alleged ineffability is our normal way of communicating. In language, the difficulty is firmly embedded within a reference system of a Self that is experienced as separate from Other, from "out there". It is a dualistic frame of reference. For example, "looking" presupposes a looker and something looked at. In Tibetan Buddhism, in contrast, there is "mind only". Everything is mind (actually its a bit more complex than that, but let's disregard it for now)

Our experienced perceptual dualism can be undone through meditation techniques. The meditator can "become" looker and looked-at, and awareness of this all simultaneously

Metaphors are indirect ways to steer the students' minds toward this, or other, goals. The mind can make use of metaphors in very creative ways, opening up new pathways and associations - something every contemporary hypnotist knows.

For example, metaphors were a key tool in the famous hypnotist Milton Erickson's hypnotic set of hypnotic techniques. It is therefore not surprising that the Mahamudra pointing out teaching methods and hypnosis have some commonalities.

Some of the standard teaching metaphors in Buddhist meditation are:

  • Ocean and Wave ( although I don´t understand how Tibetan cave yogis could translate an ocean metaphor into an inner representation!)

  • Mountain

  • Sun and Clouds

  • Mirage, City in the Sky

  • Mirror

  • Space (for the awakened mind)

  • Lamp / Butterlamp

  • Animals (dog, lion, garuda)

  • Dreams

  • Water bubbles

  • Rainbow

  • Reflections in a mirror

  • More... see my post.

The traditional Tibetan metaphors are mostly based on natural elements. Today, more contemporary and technical metaphors are usually added.

  • Cars and planes

  • Electronic devices

  • Laser sword

  • Sailboat

  • Information processing

There is more on Buddhist teaching metaphors in my post on metaphors.

The ocean and wave metaphor

The metaphor of ocean and wave is used frequently by Daniel P Brown in his 6-day meditation retreats. Phenomenologically, the meditator or meditation group is guided, using precise so-called pointing out instructions, to change their lookout position as vast, timeless, changeless, boundless awareness. The metaphor for this is the ocean and its waves. This is Brown's description:

...the practitioner refines one’s awareness so as to operate from a perspective of awareness beyond time and spatialization wherein phenomena of consciousness are experienced as an undulating timeless, ocean-like awareness within which events come and go like waves arising and passing in an ocean. Events are thus viewed from the vantage point of a changeless, vast awareness. Awareness of the field "opens up" Once this high-resolution perception is stable the practitioner recalibrates once again to a coarse-grain perception.

Keith Dowman in "Dzogchen Non-Meditation" says it poetically like this:

The second metaphor for the freely-resting nature of mind is ‘ocean’. Leaving the sense of ‘I’ and ‘mine’ behind, aware of the deceptive nature of control of either the mind or the elements, of circumstance or condition, sensory perception, either internal or external, is like the ocean, calm and imperturbable in its depths and in constant movement on its surface. The depths where no light shines and no life moves have no form or quality; the surface may sometimes appear calm but the rollers are never still – they move either in harmony or in rough and wild chaos. What is quite clear is that no mind controls the ocean. It moves without apparent logic or reason. The sensory fields have no center, and no controller determines their contents. The ocean is a metaphor for the mind and also for the sensory fields, particularly the visual sensory field. The visual field has breadth and depth and is global in shape with its genesis in the eyes. Like the ocean, this field can be still, although its calmness is deceptive as it may become rough and violent in a moment. This is our field of meditation.

The student is not asked to imagine the ever-present sound of the ocean. Instead, music is used as a support tool. This combination overlaps with the use of music in traditional shamanic ceremonies and the evolving psychedelic therapy.

The ocean in an original text

To link back the 2020 retreat to the tradition, here is an old quote (bold is original, the other text is commentary by the translator). Here I have selected a verse of Vairotsana.

"That ultimate space that is like the ocean that gives rise to the multiplicity of things; creative potential, coextensive with space, is unpredictable in the forms that it takes.
The ocean is the source of all variety. Still, in its depths, its surface spontaneously takes on all peaceful and wrathful forms representing every kind of human experience. Just as the shape of the ocean’s surface is capricious and variable, so the form of creation, the shape of our experience, is changeable, variable, and unpredictable. The creativity of the pure essence of the mind is all-pervading like space, and where it appears to manifest as this or that is always uncertain.
In the pure essence of mind, the ultimate sovereign samadhi arises spontaneously, and vision is like a vast ocean, unstructured, as extensive as space.
The creative dynamic of the pure essence of the mind is ubiquitous, although its point of apparent manifestation is uncertain. In every adventitious thought or construct, the ultimate samadhi always arises without concentration or relaxation. With that, then, vision is like a vast ocean or like the sky. Vision has no structure, or it is simultaneously structured and destructured. Thought-free with the sense of sameness, it is coextensive with space. That is the vision."

The ocean is used in particular as a teaching device or pointing out tool to ease the student into a point of observation that is calm.

This is the ocean with waves. The description is used as an analogue for the "self-calming" nature of mental movements that is a characteristic of the trained mind.

The ocean does not make an effort to re-integrate its waves or to calm them down. It all happens by itself. This encourages the Mahamudra / dzog chen meditation position where the mind exerts no effort, no activity to suppress or bring forth anything.

"Just as the great ocean observes its waves back into it, the moving events of the mind become calm of their own accord" (POW, pos tbd)
And "the metaphor of the the waveless ocean... is the most common description used for the final stage of concentration" (POW tbd)

Brown quotes Jawel Pampo:

Consider water and waves. When water arises as waves, the very water in question does not become other than water. Being nothing other than water even though it has arisen, these thoughts do not become other than their real nature [when arisen]. (PoW, pos 7078)

This metaphor only works fully, when the meditator at a deep level slips into the "identity" of the ocean. The meditator is therefore not asked to visualize an ocean out there, ie from the dualistic perspective of a watcher who watches a video of an ocean on a screen.

Instead, the student is asked to"become the ocean" and its waves, or the calm ocean.

Ocean and Waves for teaching meditation to children

The ocean and wave metaphor is also useful to illustrate the working of the mind to children. The following text is teacher instructions from "The Elephant Path. Attention Development and Training in Children and Adolescents"

Have the child imagine the mind as the vast ocean. As a thought comes, have the child notice it, and then allow it to ride off with a wave. Then, have the child allow attention to float back to the depths of the ocean where it is calm and peaceful. Children begin catching their thoughts more quickly. They begin to see thoughts coming like the wave rolling in from the ocean, and then move out to sea again so that it is possible to return to the concentration object without getting caught up in the distraction. Like the coming and going of waves in an ocean one child said "it is like looking through a camera lens at an open field. You see a bird fly by. You see it, and it goes". (page 278f).

However, not that in these instructions the purpose is not to induce a non-dual state: it is used to teach concentration.

Music as an element to represent the ocean

In this meditation retreat, Ocean and Wave metaphor instructions were usually spoken and experienced before the background of Steve Roach's " Structures of Silence" music. This music very effectively creates an atmosphere of very slow, calm, waves. It is also used by Samaneri Jayasara to read original Buddhist texts.

The student is not asked to imagine the ever-present sound of the ocean. Instead, music is used as a supportive tool. This combination has overlapped with the use of music in traditional shamanic ceremonies and the evolving psychedelic therapy

2. Ocean and waves meditation in contemplative neuroscience

This section shows one measurable effect of taking on the ocean stance.

The "Ocean and Wave" metaphor is used to induce a very specific and measurable meditative state. The metaphor and corresponding brain state are explained in a 2018 research report on the brain states of meditators.

Such research looks for the neural changes induced by contemplative activities, providing a link between hard science and Eastern meditative traditions. This is called contemplative neuroscience.

This report is a prime example of contemplative neuroscience. The following short text extract is only just the annotation of the diagram. The full text is equally highly complex and very technical and detailed.

(Note: I do not expect you to read the following excerpt word by word! I did not! Just get an idea of how the language changes from contemplative terminology to brain terminology)

Fig. 1. Change in Gamma-2  (4560 Hz) Current Density from baseline  to across states within the Anterior Cingulate  Cortex (ACC)  [BAs: 24, 32,  33]. Key: BL-          EO = baseline eyes-open/BL-EC = baseline eyes-closed/S1-2-3-4 = State 1-2-3-4.	shift towards “effortless” state from baseline to meditation onset – requiring the “settling” into initial meditation essentially characterized by timelessness (state 1: ocean & waves). Neurophysiologically, we see this in the overall reduction in brain energy (gauged in terms of current density vector) across frequencies and ROIs.		within meditation, which has now shifted one’s global experience out of the “effortful-effortless axis”, there is progressive increase in brain energy (current density vector magnitude) as the attainment of each state engages more complex executive functioning and active alertness (i.e. the brilliantly awake state of unified compassion, within state 4). However, such (‘extraordinary’) states of “awakening”
are not intentionally cognitively driven per se, rather highly effortless (and devoid of self-referential processing) to the practitioner at this stage, thus global brain energy remains lower than baseline (considered as ‘ordinary state’).

3. An short outlook on psychedelics and Holotropic Breathwork

The reported increase of gamma brain waves through the ocean metaphor (when adopted) can also be observed through increased supply or own production of the compound DMT. DMT is one of the strongest acting psychedelics.

Stan Grof, in "Holotropic Breathwork", reports that "being ocean" is one of the possible holotropic states that can be attained through his method of breathing.
