If one's eyes are kept closed, then even daytime is like night; what fault can there possibly be of the sun in this?

This couplet uses the vivid contrast between the blazing sun and willful blindness to reflect on human nature. The sun shines equally for everyone, but if we choose to keep our eyes tightly shut in denial, prejudice, or stubbornness, we will only find ourselves in darkness. It is an unfair habit to blame the world or destiny for our gloom when the fault lies in our own refusal to see. Truth and beauty are always present around us; we simply need the courage to open our eyes to them.
