The opening image holds that the flowing river never stops, yet its water is never the same water, and foam forms and vanishes without lasting. People and their dwellings are read the same way: a city looks permanent only because its turnover is gradual, and houses that seem ancient have mostly been rebuilt, with few of the old families remaining. The lens separates the persistence of a form from the persistence of its contents.
Chōmei argues that of all human folly, spending wealth and anxiety to build houses in a dangerous capital is the most pointless, because fire, wind and earthquake level rich and poor dwellings alike. The more a person invests in a house, the more he has exposed to loss and the more worry he carries. The size of the stake sets the size of the vulnerability.
Chōmei gives eyewitness accounts of the 1177 fire that burned a third of the capital, the 1180 whirlwind that tore houses apart, the 1181 famine in which corpses lined the riverbanks, and the 1185 earthquake that split mountains and toppled temples. The series works as empirical proof that security is an illusion, and it records how quickly that lesson fades from collective memory.
During the famine Chōmei notices that in households bound by deep love, the one who loves more dies first, because they give their scraps of food to the other. Mothers died while their infants still nursed at their breasts. Under scarcity, affection itself becomes a lethal cost, and the pattern of who dies reveals who loved whom.
Chōmei narrows his dwelling in stages: a family mansion, then a house one-tenth its size, then a ten-foot-square hut he can take apart and carry away on two carts. He sizes the hut to hold only himself, so there is nothing to envy, defend or lose, and he serves as his own servant so he owes no one. By cutting possessions, dependents and fixed location down to the minimum, he trades comfort for independence from both disaster and social obligation.
At the close Chōmei turns his critique on himself: the Buddha teaches non-attachment to anything, yet he has come to love his hut and his quiet solitude, which is itself a clinging. His renunciation has not freed his mind, and he can answer this only with a few murmured invocations of Amida. Simplifying outward circumstances does not dissolve the inner habit of attachment, which simply finds a new object.
