Balachandran V's poem is about the ways we protect ourselves from our own inner truth. The speaker says "we" keep our eyes shut and our ears closed, and the reason is fear. Not fear of the outside world, but of what we might see in ourselves and hear from our own hearts. The shutting-out is deliberate, a kind of hiding from our own honesty.
In the last stanza, the body gives us away. Hands shiver and the mind hesitates, and these small signs show that we already understand what we're avoiding. The repeated "we know / we know" lands like a quiet admission, as if the speaker has finally stopped pretending. The closing line, "what we do not want to know," sums up the contradiction: we can't unknow something we have already sensed.
The mood is hushed and uneasy, but also gentle. The speaker doesn't scold anyone. The ellipses leave each thought trailing off, which suits a poem about things we hesitate to say out loud.
