Gitanjali: 29

He whom I enclose with my name is weeping in this dungeon. I
am ever busy building this wall all around; and as this wall goes up
into the sky day by day I lose sight of my true being in its dark
shadow.
I take pride in this great wall, and I plaster it with dust and sand
lest a least hole should be left in this name; and for all the care I take
I lose sight of my true being.
