A blind speaker chases sounds across stones, and then the sounds vanish. That is the whole story, and the poem tells it in short, breathless lines that feel like the running itself.
The speaker starts with a plain statement, "I m blind," and then goes further: "Mind went dark." The darkness seems to be inside as well as outside. With no sight, the speaker follows sound, the only guide left. The word "Blindly" repeats the idea, and "Running fast" shows how urgent and a little reckless the chase has become. The stones suggest uneven, hard ground, so the speaker may stumble.
Then comes the single word "Stop." with its full stop, and the rhythm breaks. "Sounds disappeared." Nothing is left to follow. The mood moves from frantic energy to sudden emptiness, and the poem leaves us in that silence, feeling the speaker's disorientation and loneliness. The missing apostrophe in "I m" also gives the opening a rushed, unpolished feel.
