The question of gentrification is made complex by the fact that the urban qualities it produces—lively street life, profuse commerce, preservation and upgrading of old buildings—are highly desirable, the substrate of urbanity. The problem with gentrification is with its particulars and with its effects.
Gentrification suppresses reciprocity by its narrowed scripting of formal and social behavior, by turning neighborhoods into Disneylands or Colonial Williamsburgs, where residents become cast members and the rituals of everyday life become spectacle or food for consumption.
It is related that the bodhisattva Manjusri was once standing at the gate, and seeing him, Shakyamuni Buddha called to him, "Manju, Manju, why don't you come inside the gate?"
Manjusri replied, "I don't see anything outside the gate."
When you once attain true self-realization, these barriers disappear in an instant as though they were nothing but mirages, and you will find that from the very beginning you have always been in a world where there is neither inside nor outside. That is what "gateless" means. Therefore, all koans are impassable barriers for those who are unenlightened, but for the enlightened there is no gate at all. They can come and go quite freely.
One day, as Kyogen was clearing the undergrowth, a pebble bounced off the tip of his broom and resounded against a bamboo tree. Hearing the sound, he suddenly experienced great enlightement. The first stanza of the poem he composed on this occasion is very famous:
One striking sound,
and I have forgotten all I knew.
