Sesshin, (literally “touching the heart-mind”) is an intensive Zen retreat that is structured to guide us in the persuit of finding our true self, which is another expression for breaking through the barrier of dualism.
To this end, a sesshin consolidates all Zen-practices for this purpose and provides the support that is required for an extended practice period of between 5 and 7 days.
Sesshin is made up of various practice forms that allow us to experience, through mindfulness, the interconnection of all activities. This is achieved through a disciplined structure that engages us seamlessly throughout the entire sesshin.
During a sesshin, our personal commitment to silence binds all practices and activities together. Silence cultivates and heightens our awareness and mindfulness, which lessens our internal and external need to differentiate.
The practice of silence is thus a practice that aims to reduce our desire to add layers of commentary to our activities which aids our practice of concentration. Through the focused concentration of what is at hand (sitting, eating, cleaning..), we build up joriki (concentration momentum), which in turn strengthens our capacity to hold and direct our concentration in order to unbind us from our constant conceptualising. Once freed from this cycle, even for a short period, a new perspective can open.
Every lapse into mindless speech or intellectual gratification can take us away from our practice at a sesshin and can thus contribute to a weakening of joriki. Joriki is cumulative and thus builds over the sesshin period.
Silence can be seen as the vein through which all sesshin practices flow and function. The disruption of silence is to be avoided at all cost as once the flow of silence is established, it takes great effort to reestablish.
A sesshin has a unique character which unfolds as we surrender to our sesshin activities. In a sesshin, we shift our focus from ourselves and instead allow ourselves to simply experience what is at hand.
How to work with the sesshin rituals:
Samu practice (Housekeeping)
Kitchen work practice, toilet cleaning practice, arranging your bedding practice, vacuum practice, photocopying practice, outside window cleaning practice…
The practice of Samu is similar to other activities or ritual practices and grounds us to our ordinary day-to-day activities. Samu, if practiced in this way, can be seen as being no different from zazen. Samu practice can give us a glimpse of what every koan and dokusan presentation is all about. Samu is a mindfulness practice that can challenge our perspectives and conceptualisations of our work.
Chanting and recitation practice
This practice is the daily repetition of Zen chants mainly derived from Buddhist sutras. They represent condensed teachings that have been handed down to us, from our lineage, throughout the ages. They are a reminder of how to practice correctly and warn against delusive interpretations. They can be seen as benchmarks to guide us along the way and compare our state of mind with those that have gone before us on the same path. When our experience mirrors that which is written in these texts, we can be assured that we are on the right track. We can also gauge in them, how far we still have to go. If we can’t understand what is said in the texts, we have perhaps not realized what these sutras point to. They spur us on, encourage us to keep going. They are motivators. Practicing the chants together also holds value as we share this journey with fellow practitioners. Ultimately, like every Zen ritual, the recitations are just recitations, complete in themselves, with nothing to add.
At Sesshin, the concentration power or joriki of both, the student and the teacher, is heightened. Because of this, dokusan can seem more intense than when experienced during the weekly dokusan. It moves to another level, which is another benefit of participating in a sesshin.
Dokusan practice, especially for those working on koans, takes on a momentum that is directly linked to the joriki gained during sesshin.
Koans can seem more alive as we get more clarity and insights through our elevated focus during the sesshin practices.
It is difficult to get to this level of clarity without the practice intensity during sesshin.
The value of a teisho is not so much what is said but what happens during the process. This is because a Teisho, unlike a Dharma talk, is a talk about a koan and thus designed to present and to point to the absolute.
When I hear a teisho, it gives me a certain assurance and feeling that the process as practiced in Zen is right. I usually forget the words that have been said but I do not forget the feeling I experience when I hear it. It touches something in a way that nothing else does. It resonates to the core of who I am. Of course not every teisho does this, but that is the purpose of a teisho compared to a regular Dharma talk which is usually about a teaching or practical aspect of the Dharma. Sometimes it may only be one sentence or one demonstration in the whole of a teisho, but when it happens it is invaluable for our practice as it may dislodge some of our habitual ways of looking at things.
A teisho is therefore not necessarily about content, but about recognising our true-nature through the process of delivery.
A teisho is an important part of sesshin practice as what touches us at our core, has a way to work on us, perhaps unconsciously, through the process. Also, I think that participants in a sesshin, exhibit, through their heightened receptiveness or awareness, an ability to intimately connect with what is presented.
Sangha and precept practice
To my way of thinking, this is perhaps one of the most important aspects of a sesshin. Our Sangha is not just our fellow sitters. It extends to all beings, which are of course nothing other than our true-self.
The relationship we have with the world we live in is thus nothing other than the relationship we have with ourselves.
Being in Sesshin is therefore a practice that allows us to experience this relationship directly and intimately.
The limitations of our practice are shown-up the most in our relationships we have with our family, friends and Sangha. A sesshin thus offers us a mirror, which shows up our delusions and offers a practice-path to go beyond them.
In a sesshin, our conduct, especially our “mental” conduct is exposed through our heightened awareness and mindfulness practice. If our thoughts, speech and actions do not align with our values (precepts), it shows up. This can be a very unpleasant experience as we are confronted with our shortcomings in the form of annoyances, judgments, and general ego confrontations. It is all the more painful, when we realise that we cannot simply turn of this mental anguish.
Sangha practice keeps us honest as it ultimately validates or invalidates our entire Zen practice. Our shortcomings are reflected over and over again in our relationships, which is just another word for Sangha.
Yamada Kôun Roshi once stated that the ultimate purpose of Zen is the development of our character. Zen practice is thus a practice to develop peace with “other”, which is the same as being at peace with our true-self.
Sangha practice is therefore precept practice, as the precepts are the tools and guidelines by which we guide our conduct. Precept practice thus forms an integral part of Sesshin practice.
Zazen can be seen as a means to an end. That is, a concentration and wisdom practice that may eventually lead to a breakthrough and a shift in our perspective to experience the collapsing of our dualistic way of experiencing ourselves and the world.
Once this breakthrough or kensho is achieved, zazen is no longer experienced as a means to an end, but instead is no longer distinguished as a separate practice or activity from our all other activities. Zazen is experienced as both beginningless and endless.
Zazen draws all practices together as when we realise it directly, we no longer are bound by our conceptual and dualistic limitation of what we think it is. That is why Dogen said that zazen and enlightenment are one and the same.
This does not mean however that we drop the practice of zazen once we reached a certain level of awareness, that, misses the point entirely as the goal is the path at every stage and the path is endless.
Zazen practice can be seen as the driver of all practices, without which, we are easily diverted into delusive thinking.
A consistent and earnest daily zazen practice is a sign of a mature practice.
