The Scholar Who Slept Well in the Cold

Song Lian had no algorithm, no sleep tracker, no weighted blanket. He had a quiet mind. It turned out to be enough — and more than enough.

Song Lian — the great Ming dynasty scholar, teacher of the Hongwu Emperor, author of some of the most elegant prose in classical Chinese literature — is remembered today mostly for a short essay that every Chinese student has memorised and most have forgotten to actually read.

Song Dongyang Ma Sheng Xu — "A Farewell Letter to Ma Sheng of Dongyang" — is, on the surface, a piece of advice to a young student about the value of hard work. But read carefully, it is something more interesting: a quiet argument about the relationship between material conditions and inner peace, written by a man who had tested that relationship against the hardest possible circumstances and arrived at a conclusion that still surprises.

Song Lian lived to seventy-two — an extraordinary age for the fourteenth century. He did so not despite the hardships of his early life but, in some sense, because of what those hardships taught him about the only condition that actually matters for rest: the quietness of the mind that has nothing left to want.

The Cold Room and the Quiet Mind

In the essay, Song Lian describes his years as a young scholar seeking education in conditions of genuine deprivation. The ink freezes in the inkstone. His fingers cannot bend. He walks hundreds of li through snow to reach a teacher, arriving with his feet so cold they have lost sensation. He sleeps in unheated rooms, eats simple food, wears clothes that offer little protection against the winter.

And yet — and this is the part that deserves more attention than it usually receives — he does not describe himself as suffering. He describes himself as content.

"Although my body was not as well-provided for as others," he writes, "I had no sense of envy. Because the joy I found in my studies was sufficient to overcome the discomfort of my circumstances."

The body that is at peace with its circumstances sleeps. The body that is at war with them does not. This is not a metaphor. It is physiology — the oldest sleep science there is.

What Song Lian had discovered, through necessity rather than philosophy, is what every tradition of contemplative practice has arrived at through deliberate cultivation: that the quality of sleep is determined less by the conditions of the body than by the state of the mind. A quiet mind sleeps in a cold room. An agitated mind lies awake in the finest bed that money can provide.

Movement: The Body That Walked to Knowledge

Song Lian's account of his education is, among other things, an account of extraordinary physical effort. He walked distances that would exhaust a modern person with good shoes and a full stomach. He carried books. He climbed. He arrived, repeatedly, at the point of physical exhaustion — and slept.

There is a lesson here that is easy to miss in its simplicity: the body that has genuinely used itself during the day has no difficulty sleeping at night. Not because exhaustion forces sleep, but because the body that has moved purposefully through the world has discharged the physical energy that, left undischarged, becomes the restlessness that keeps us awake.

The Confucian tradition that Song Lian inhabited understood this as xiu yang — the cultivation of the self through the disciplined use of the body as well as the mind. Movement was not exercise in the modern sense — a scheduled intervention to compensate for a sedentary life. It was simply what a person did: walked, worked, engaged physically with the world, and returned at the end of the day to rest that was genuinely earned.

An evening walk. The deliberate use of the body in the hours before sleep. Not performance, not optimisation — simply the honest expenditure of physical energy that the body was designed to spend.

Nutrition: The Freedom of Needing Less

Song Lian ate simply. Not by choice, initially — but he discovered, as many people who have been forced into simplicity have discovered, that the body's actual needs are considerably more modest than its appetites suggest.

He describes the wealthy students around him with their elaborate meals and fine clothing, and notes, with a calm that reads almost like amusement, that he felt no particular desire for what they had. His food was sufficient. His body was nourished. And because his digestive system was not burdened by excess, his sleep was not disturbed by the work of processing what it had been given.

Traditional Chinese Medicine has always understood the relationship between the evening meal and the quality of sleep. The spleen and stomach, which govern digestion in the classical body, are at their most active in the morning and early afternoon. By evening, their energy is declining. A heavy meal at this hour is a demand made of a system that is trying to rest — and the body, obedient, stays partially awake to meet it.

The scholar's evening meal: warm, simple, sufficient. Congee with a handful of red dates. A cup of longan tea. Food that nourishes without demanding, that sustains without burdening, that allows the digestive system to complete its work before the hour of sleep arrives.

Song Lian would have recognised this not as deprivation but as wisdom — the freedom that comes from needing less than you thought you did.

The Bedtime Ritual: From Nothing to Something, Chosen with Care

Here is where Song Lian's story takes its most interesting turn.

He slept well in the cold room with the frozen ink and the inadequate blanket. He slept well because his mind was quiet, his body was tired, and his spirit was at peace with its circumstances. He needed nothing more than he had.

But the essay is not an argument for deprivation. It is an argument for sufficiency — for the recognition that what we need is less than what we want, and that the gap between the two is where most of our suffering lives.

When Song Lian eventually rose to prominence — when he became the teacher of an emperor, the author of the official history of the Yuan dynasty, one of the most celebrated scholars of his age — he did not abandon the simplicity he had learned. But he also did not refuse the good things that came with his position. He understood the difference between grasping and receiving: the grasping mind is never satisfied; the receiving mind accepts what is offered with gratitude and uses it well.

To sleep on mulberry silk, in this spirit, is not an indulgence. It is a form of gratitude — the recognition that the body, which has served you faithfully through the day, deserves to be received by something worthy of it. Silk regulates temperature through the night, moving with the body's natural fluctuations rather than imposing its own. It is smooth against the skin, gentle on the hair, quiet against the nervous system. It asks nothing. It simply receives.

Song Lian slept well with nothing. The question his story asks us is: now that you have something, are you sleeping any better? And if not — what is it, exactly, that is keeping you awake?

Sleep Quality: The Oldest Prescription

We live in an age of sleep solutions. There are apps and devices and supplements and weighted blankets and white noise machines and AI-powered sleep coaches that promise to analyse our rest and tell us how to improve it. The global sleep economy is worth hundreds of billions of dollars and growing.

Song Lian slept in a frozen room with no solutions at all, and woke each morning to walk through the snow to his teacher's house.

This is not an argument against comfort. It is an argument for honesty about what comfort can and cannot provide. The conditions of sleep matter — temperature, darkness, the quality of what touches the skin, the hour at which we lie down. These things are real, and they are worth attending to.

But they are not sufficient. The mind that is at war with itself will not be quieted by silk, however fine. The spirit that is consumed by anxiety will not be soothed by darkness, however complete. The self that cannot stop wanting will not find rest in any bed, however carefully designed.

In the age of artificial intelligence, when we are offered ever more sophisticated tools for managing our inner lives from the outside, Song Lian's essay offers a different kind of technology: the ancient, unglamorous, endlessly effective practice of wanting less, accepting more, and arriving at the pillow with a mind that has nothing left to argue with.

Create the conditions. Choose the silk. Dim the light. And then — as Song Lian did in his cold room, six hundred years ago — let the quiet mind do what it has always known how to do.

Carried Into Sacred Spaces

Song Lian understood that some forms of peace cannot be earned through effort alone — that there are places where the accumulated weight of prayer and intention creates a stillness that the individual mind cannot manufacture on its own. Every month, we journey to ancient temples and Taoist sanctuaries across China — lighting incense, offering prayers, and carrying the intentions of our members into those sacred spaces. Those who walk with us for six months or more will receive, at year's end, a curated collection of sacred tokens gathered from the altars and shrines along our path — small objects that hold the memory of incense smoke, mountain silence, and whispered prayers. Each piece travels from a place of stillness to find its way to you. Discover the Journey →🕯️🏮☯️
