Tagore reacted to the halfhearted uptake of modernist and realist techniques in Bengali literature by writing matching experimental works in the 1930s. These include "Africa" and "Camalia", among the better known of his latter poems. He occasionally wrote poems using "Shadhu Bhasha", a Sanskritised dialect of Bengali; he later adopted a more popular dialect known as "Cholti Bhasha". Other works include "Manasi", "Sonar Tori" ("Golden Boat"), "Balaka" ("Wild Geese", a name redolent of migrating souls), and "Purobi". "Sonar Tori"'s most famous poem, dealing with the fleeting endurance of life and achievement, goes by the same name; hauntingly it ends: "Shunno nodir tire rohinu poŗi / Jaha chhilo loe gêlo shonar tori"—"all I had achieved was carried off on the golden boat—only I was left behind." "Gitanjali" () is Tagore's best-known collection internationally, earning him his Nobel.
