How did Hari feel after spending some time in the river?

After spending time in the river, Hari actually felt a sense of exhilaration and rejuvenation, which aligns more with feelings of relaxation or contentment rather than feverishness. The experience of being in the river often brings a feeling of relief and comfort, particularly in the context of his struggles. It provides a break from the harsh realities he faces in his life, allowing him a moment of peace and tranquility. The coolness of the water typically offers a refreshing contrast to the heat and difficulty of his circumstances, enabling him to recharge emotionally and physically. Thus, feelings of exhaustion or feverishness would be contrary to the liberating and fresh emotions associated with such a natural experience.
