Sanshin 三心: The Three Minds of the Buddhist Kitchen

In Sapporo, the winter tap water runs cold, numbing your fingers in seconds. The feeling brings back memories of my time training at Enryaku-ji on Mt. Hiei. But now I am in my own kitchen, surrounded by modern appliances and the sounds of the city. Yet every morning as I wash the day’s rice until the water runs clear, the internal work remains exactly the same. Whether you are a monk in training or a home cook preparing dinner after a long day, the physical act of cooking is the easy part. The real challenge — and the real practice — lies in sanshin, the Three Minds. If the heart is not aligned, the meal is already compromised before the fire is lit.

The Tenzo's Inner Work

In the traditional hierarchy of a Japanese temple, the tenzo (head cook) holds a position of immense spiritual responsibility. The Tenzo Kyōkun, written by the Zen master Dōgen in 1237, articulates this responsibility most clearly. Though Dōgen is associated with Sōtō Zen, he began his path as a Tendai monk on Mt. Hiei, and the principles he codified transcend sectarian lines. They belong to the broader Mahayana tradition, and they teach something that most modern cooking philosophy ignores entirely: that the quality of a meal begins not with technique or ingredients, but with the mental posture of the person preparing it. The tenzo. The cook.

Sanshin 三心 — three specific mental attitudes — transforms the kitchen from a place of labor into a place of awakening. In the previous article on shun (旬), we explored how the temple cook reads the seasons to know when to act. Sanshin addresses something more fundamental: how to be present while acting. Where shun governs the cook's relationship to time, sanshin governs the cook's relationship to self.

Kishin 喜心: Joyful Mind

Kishin is the cultivation of deep, unconditional gratitude for the work itself.

In daily life, it is easy to view cooking as another task on the list — something standing between us and rest. Kishin inverts this. It asks us to rejoice in the fact that we have ingredients to cook, a kitchen to work in, and the health to stand at the counter. It is a mind full of gratitude.

In my own kitchen in Sapporo, this manifests as a shift in energy the moment I return home with a backpack full of groceries. Instead of viewing the prep work ahead as an obligation, I try to see it as a rare privilege — the same privilege the tenzo in a mountain monastery recognizes when they prepare food for the sangha.

In monastic language, we say the cook serves the Three Jewels: the Buddha, the Dharma, and the Sangha. At home, the sangha may be nothing more than your family gathered around a table, or even yourself eating alone. The scale does not diminish the practice.

This joy is not contingent on having expensive ingredients or a well-equipped kitchen. It does not arrive after the perfect dish comes together. It arises from the vow to serve, and it precedes every other action. A cook who can wash spinach with a light heart transmits something through the food that no amount of technical skill can replicate. There is a palpable difference between a meal assembled in resentment and one prepared with kishin — and anyone who has eaten both knows it without being told.

When I was a young chef, getting my start in the French kitchens of my hometown, Boston, the chef often said he could tell which dishes I enjoyed plating versus the ones I didn’t just by looking at them. This taught me even before my Buddhist practice began about the tangible effects of kishin.

Rōshin 老心: Parental Mind

Rōshin, sometimes translated as "grandmotherly mind" or "parental mind," is the attitude of selfless, protective care.

The Tenzo Kyōkun instructs the cook to treat ingredients as if they were their own eyes — with that degree of care and attentiveness. Just as a parent protects a child from the cold without hesitation or calculation, the cook protects ingredients from waste and the diner from harm.

This is the spiritual engine behind ichibutsu zentai, the principle of whole-food cooking that we will explore later in this series. A cook who possesses rōshin handles a humble potato with the same delicacy they would bring to a rare and expensive truffle. It is visible in how we peel a daikon radish — carefully trimming away the fibrous outer layer, preserving the flesh — and in how we save those peels to make a simple kinpira sauté or add them to a soup rather than discarding them. It is the meticulous attention to temperature, to texture, to the eater's comfort, even when the cook is tired.

Rōshin dissolves the boundary between the one who uses and the thing being used. When we handle a vegetable with rough indifference, we dull our own sensitivity in ways that extend far beyond the kitchen. When we handle it with the care of a parent, we practice maitri — loving-kindness — in its most concrete and unglamorous form. Under the influence of rōshin, "leftovers" become sustenance and what might have been waste becomes resourcefulness.

Daishin 大心: Magnanimous Mind

Daishin, or "vast mind," is the mind of equanimity and impartiality.

The classical description compares it to a mountain — stable, unmoved by weather — and to the ocean, which receives every river without preference. It requires the cook to remain unswayed by the seasons of circumstance: neither overly proud when a dish succeeds nor devastated when it fails.

In practical terms, daishin liberates the cook from bias. A chef with vast mind does not favor the expensive melon over the common cabbage. A single leaf of greens receives the same reverence as a lavish banquet spread. In the supermarket, we might desire the finest produce, but daishin allows us to accept what is actually available and make the absolute best of it without complaint.

We bring our prejudices to the cutting board more often than we realize — valuing imported "superfoods" while overlooking the local root vegetable, treating an elaborate dinner as more worthy of attention than a simple breakfast. Daishin challenges all of this. It asks us to remove the distorting lenses of our discerning mind and meet reality exactly as it presents itself. The kitchen that operates under daishin becomes calm, focused, and resilient — a sanctuary that remains steady regardless of what the day has thrown at the cook.

Sanshin as Daily Practice

The three minds are not attitudes to be perfected before cooking begins. They are cultivated through cooking — in the same way that a meditation practice deepens through daily sitting, not through reading about meditation.

The next time you stand at your kitchen counter, before reaching for a knife or turning on the stove, take a single breath. Notice the ingredients in front of you. Allow yourself a moment of gratitude for the food and the ability to prepare it — this is kishin. Pick up one vegetable and hold it with both hands, feeling its weight, committing to waste nothing — this is rōshin. Then let go of the desire for the meal to be perfect or impressive, and simply commit to being present with the task — this is daishin.

The shift is quiet, almost imperceptible from the outside. But over weeks and months, this practice rewires the cook's relationship not only to food but to every act that requires attention and care.

The Kitchen Light

The steam rising from a bowl of soup is just steam. But the mind that created it changes everything.

When we cook with the Three Minds, the soup becomes more than hot water and vegetables — it becomes a transmission of attention, care, and equanimity. We may live in the modern world, wearing work clothes instead of robes, commuting instead of walking mountain paths, but every time we wash rice or slice a carrot, we have the same opportunity: to turn the simple act of cooking into mindful practice.
