The speaker is spending his first Onam without his mother, after forty-six with her. Around him the festival goes on: new clothes, TVs, fridges, shopping. But for him it only sharpens the loss. "Onam will come, the dead will not."
He then turns to nature, which keeps flowering and greening, and finds a thin comfort: life continues despite death. From there he imagines meeting his mother again in a newborn, holding her, recognising her by smell, and finally saying the love he never expressed.
What stands out is his honesty. He admits the relationship was hard, with bitter words and "walls" of hate, even though he cared for her to the end. The images of a whipped horse and a kicked dog suggest guilt and confusion. The mood is sorrowful and regretful, ending in a longing for time to run backward to a child's safe sleep on her lap.
