"Once a holy man came to the bank of the Ganges and lived near the bathing-ghat at Ariadaha, not far from Dakshineswar. We thought of paying him a visit. I said to Haladhari; 'Krishnakishore and I are going to see a holy man. Will you come with us?' Haladhari replied, 'What is the use of seeing a mere human body, which is no better than a cage of clay?' Haladhari was a student of the Gita and Vedanta philosophy, and therefore referred to the holy man as a mere 'cage of clay'. I repeated this to Krishnaldshore. With great anger he said: "How impudent of Haladhari to make such a remark! How can he ridicule as a "cage of clay" the body of a man who constantly thinks of God, who meditates on Rama, and has renounced all for the sake of the Lord? Doesn't he know that such a man is the embodiment of Spirit?' He was so upset by Haladhari's remarks that he would turn his face away from him whenever he met him in the temple garden, and stopped speaking to him.

Do not look to a saint or a person who has renounced everything for the sake of God as ‘just another person’ or disrespect him. He is an embodiment of Spirit. God resides in the hearts of Such holy men.
