Kukai's Wisdom for Letting Go of an Overpacked Schedule: A Simple Art of Time for Those Who Leave No Room to Rest

Why We End Up Filling Every Hour of the Day with Plans

Open your planner or calendar app and plans are packed in densely from morning to night. When there is a free slot, you cannot help wanting to fill it with something. Even on a day you decided to rest, you add errands, thinking "I really should get that done too." Does this way of living sound familiar?

Behind our packing in of plans lie several psychological forces. One is the belief that "time spent doing nothing is wasted." Within a society that prizes productivity, we have come, without realizing it, to feel guilt over empty time. Another is the illusion that busyness somehow proves our worth. When the schedule is full, we feel we are needed, that we are living properly. And so, unconsciously, we fear the blank and fill it in.

Yet when you finish a day packed full of plans, what remains is not deep fulfillment but, somehow, only a worn-down kind of fatigue. Have you not had that experience? In fact, within the teachings of Kukai, who founded Shingon esoteric Buddhism twelve hundred years ago, there is a hint for rethinking this "overfilled life" from its very roots. It is the thought that values ma — meaningful space — and emptiness. In this article, we introduce that wisdom and a simple art of using time in daily life.

The Thought of Ma and Empty Space That Kukai Valued

In the esoteric view of the world that Kukai conveyed, all things exist by relating to and resonating with one another. And it is precisely in the space between things, between one sound and the next, between one act and the next, that deep meaning dwells. Calligraphy, practice, ritual — none takes form by merely stringing motions together. The ma, the interval, between one movement and the next is what gives breath and rhythm to the whole.

Kukai himself was renowned as a master calligrapher, later honored as one of the "Three Brushes." In calligraphy, the empty space between one character and the next, the space where no ink is laid, is valued as much as the characters themselves. Without empty space, the characters merely smear into black and become unreadable. It is precisely because there is space with nothing written that the written characters come alive and the whole rises up beautifully.

This applies directly to how we use time. Without ma between one plan and the next, each act merely flows past in a rush and is not carved deeply into the heart. Empty space is not vacant, idle time, but an active space that lets prior experience soak into the heart and prepares us for the next act. Kukai's thought quietly teaches that emptiness is precisely what gives breath and rhythm to life.

How an Overpacked Schedule Affects Body and Mind

A life packed too full of plans does not end at merely "being tiring." Research in brain science has found that during "idle time," when a person appears to be doing nothing, the brain becomes active in organizing memories, linking thoughts, and reflecting on oneself. This state is indispensable for creativity and inner ordering. Fill every gap with plans, and the brain loses the time to do this vital work.

Moreover, when constantly chased by the next appointment, a person can no longer place their heart in the here and now. Even while savoring the meal before you, your head is full of the next errand. Even while talking with the person beside you, your heart is watching the clock. Thus each precious experience passes by without ever reaching the heart. Within busyness, the very texture of life grows thin.

Further, a life without margin robs us of inner room as well. When plans are packed tight, a single plan going awry can collapse the whole day. We grow excessively irritated at small delays and troubles, and can no longer be kind to others. Conversely, with margin between plans, room arises to absorb the unexpected. Empty space serves as an invisible cushion that lets the heart stay supple.

The Days I Felt Guilty Leaving a Blank in My Planner

Let me share something of my own. The me of before could never settle when there was a blank in my planner. With nothing scheduled on a weekend, I grew restless, thinking "am I wasting this time?", and would try to fill it even by hunting up errands. There was even a period when I wrote rest itself into my planner as if it were a task to be done.

Once, on a day off when, unusually, I had scheduled nothing, I was simply gazing absently at the sky from my balcony. At first there was the restlessness of "doing nothing." But as I watched the drifting clouds for a while, something that had quietly nagged at a corner of my heart for months suddenly, calmly sorted itself out. It was a thought that had never once surfaced while I was bustling about.

What I realized then was that the blank time I had feared as "waste" was in fact necessary nourishment for the heart. Empty space was not time without doing anything, but time for the heart to work quietly and for me to recover myself. Since then, I have made a point of leaving time in my planner deliberately blank. I learned, through my own body, how much lighter the heart becomes when you leave the blank without fearing it.

Five Practices from Esoteric Buddhism for Reclaiming Empty Space

From here, I introduce five practices for bringing Kukai's thought of ma into how we use time each day.

First, deliberately build empty space, doing nothing, between one plan and the next. Rather than packing meetings and errands back to back, place a ma of ten or fifteen minutes between them. That blank becomes the breath that lets one act soak into the heart and lets you move calmly to the next.

Second, create a "sanctuary with no plans" somewhere in the day. Decide, for instance, that fifteen minutes in the morning or thirty minutes at night is time with nothing scheduled. Guard that time as blank. This is not laziness but active empty space, secured intentionally for the working of the heart.

Third, decide not to feel guilt over blank time. Reframe time spent doing nothing not as waste but as vital time for the brain to organize thoughts and for the heart to recover itself. This shift in thinking alone greatly changes how you relate to empty space.

Fourth, when you finish one act, do not leap straight to the next — set a breath in between. After a meal, after work, pause for just a few breaths. That small ma gives a sure punctuation and rhythm to a day that tends to rush past.

Fifth, before adding a plan, ask once, "Is this truly necessary?" Many of the plans we try to add in order to fill a blank may be born of anxiety about busyness. Simply pausing to ask anew gradually makes life simpler and opens up margin for what truly matters.

Time Spent Doing Nothing Is What Deepens a Life

The thought of ma that Kukai valued belongs not only to the world of calligraphy and practice. It delivers to us moderns — so apt to lose even the margin to rest under an overpacked schedule — a quiet and certain wisdom for re-ordering life toward simplicity.

Just as the empty space between characters brings the whole of a calligraphy to life, so in living, it is the ma between one plan and the next that lets each experience reach the heart and gives life its breath and rhythm. Blank time that appears to be doing nothing is by no means waste, but irreplaceable nourishment for the heart to recover itself and deepen its thoughts.

If you feel, right now, chased by plans and unfulfilled though you are supposedly resting, try leaving just one blank in tomorrow's planner, deliberately writing nothing. At first you may feel restless. But it is precisely in that blank time that something important, left behind amid the busyness, will quietly return. What enriches a life is not adding more plans, but leaving, without fear, the empty space of doing nothing.
