Engaging our Circle of Presencing Emptiness 

In Zen culture that developed in Japan the use of the Enso in art and 

calligraphy is pervasive, where the Enso circle is the most popular of 

calligraphies.  The historical roots go back to India, where the initial concept 

of zero was represented by the bindu or dot, the intrinsic spirit-life seed within all 

reality. This later evolved into the circle or Sunya and then to the Buddhist 

paradoxical idea of Emptiness or Sunyata - the ‘empty’ (sunya) that is completely ‘full’ 

(ta).  The prajna paramita/ heart sutra describes this paradoxical view:

 

Form is emptiness (sunyata), emptiness is form;

Form is no other than emptiness, emptiness no other than form;

That which is form is emptiness, and that which is emptiness is form.

The same is true for all the skandas: form, feeling, thought, volition, discernment 

 

The 6th century Hsin Hsin Ming authored by the 3rd Great Ch’an/Zen Ancestor, Seng T’san, 

would use the image of ‘round and perfect’ equating to ‘great space’ in speaking of the ultimate

 completion:

 

Round and perfect like great space.

Nothing lacking, nothing in excess

 

In the European West, the 15th century philosopher and mystic, Nicholas de Cusa 

writes of: 

“…the likening of an infinite circle to oneness.” 

And that: 

“God is an infinite circle…an infinite sphere.” (On Learned Ignorance ch. 21) Later, the 

French 17th century Philosopher Blaise Pascal would intuitively echo the 

Buddhist idea in his rationalistic theology:

 

“God is that circle whose center is everywhere and circumference nowhere”.

 

In the late nineteenth century, theosophic mystic, Helena Blavatsky, through her ‘transmural view’ 

of a ‘boundless principle’ which bridges the ideological gap between East and West. She

anticipated 21st century theoretical physics, by initiating the idea of a ‘Zero point’ or boundless 

circle; a fulcrum point, intrinsic to the universe itself. (The Secret Doctrine v.I p.601)

 

The Zen monk/artist of the late 18th century, Sengai, fills his Enso drawing 

with both wisdom and humor. He draws an Enso and writes next to it:

 

“Eat this and have a cup of tea!”

 

So, the reality is placed in front of us and invitation is offered for 

us to ‘eat this’; the Enso, the ultimate Zero of (shunyata) emptiness. 

This is not a theoretical idea or abstraction but placing our attention 100% in this present moment 

in the act of drinking tea. How to drink this cup of tea with undistracted, seamless unity of our 

awareness; tea, awareness and drinking tea as one act. 

Engaging this seamless practice, moment after moment in our daily life is Zen.

ENSO ZEN

‘Enso Zen’ could also be termed ‘Wabi sabi Zen’ or the ‘Zen of the Natural 

World’.  A Zen monk is called an ‘Unsui’, literally ‘Cloud-Water’, someone whose 

activity is unified with nature, to float like a cloud and flow like water. 

Succinctly expressed:

 

Flowing water

Does not

Argue

With itself

-Tashiro Roshi

 

So, this ‘flowing water’ as an image gives us pause to engage, then to see and 

BE the non-dual state. 

In Zen philosophy, the Enso symbolizes the unity of subject and object, space 

and time or Being-Time (Uji) 

Sasaki Roshi says: 

“Not only self, but everything, exists with space as body and time as its 

content. In the case of self, the body is space and the mind is time. It is 

impossible for either body or mind to exist independently. Self means the action 

of oneness of body and mind. This world, too, is the action of oneness of space 

and time. Therefore, it is said in Buddhism, that this world is the action of 

the interdependence of the two things.”

 

So, from this viewpoint, Enso is simultaneously the container and contained, in 

the process of containing.

 

Sasaki Roshi also speaks of Buddha as ‘the center of gravity’. Yet it could also 

be said that ‘Buddha is NO center of gravity’ or ‘Zero is NO zero’ …and Enso 

that is NO Enso. Everything is complete ‘As It Is.’

The following poetic Zen saying expresses the simultaneous paradoxical oneness 

of the relative and unified VEIW in the following image: 

“One moon shows in every pool; in every pool the one moon.”

Ken Shuho Small

Throughout the 1970s and into the 1980s, Ken Shuho Small studied and practiced Zen with Joshu Sasaki Roshi, Genei Tashiro Roshi and into the present time with Sandy Gentei Stewart Osho. In 1971, Ken received lay vows and his Zen name, Shuho, from Joshu Sasaki Roshi.

Since the mid-1970s, he has been deeply involved in cooperative community development, ethnobotany, and herbal medicine. Ken has also engaged in and promoted the indigenous spiritual and healing traditions of Mexico and the Americas. Since the 1990s, he has hosted scores of teachers from all schools of Tibetan Vajrayana traditions, especially Dzogchen; viewing its common roots in practice with Zen.

Ken is curator and collaborator of the Perennial Wisdom Resource Collection and the Lomaland Community Theosophy Archive at San Diego State University’s Special Collections and University Archives.

With the help of others, Ken established The Enso Project in 2018. He now serves as The Enso Project’s ‘vision holder’ and guiding facilitator for Zen practice.
