Lord Caitanya was very much pleased by this behavior of Sanātana's, but He noticed the valuable blanket that had been given to him by his brother-in-law while Sanātana was en route to Benares. Although Lord Caitanya did not say anything about the blanket, Sanātana understood that He did not approve of such a valuable garment on his body, and therefore Sanātana decided to get rid of it. He immediately went to the bank of the Ganges, and there he saw a mendicant washing an old quilt. When Sanātana asked him to trade the old quilt for the valuable blanket, the poor mendicant thought that Sanātana was joking with him. "How is this?" the mendicant replied. "You appear to be a very nice gentleman, but you are mocking me in this unmannerly way."
"I am not joking with you," Sanātana informed him. "I am very serious. Will you kindly exchange your torn quilt for this blanket?" Finally the mendicant exchanged his torn quilt for the blanket, and Sanātana returned to the Lord.
"Where is your valuable blanket?" the Lord immediately inquired. Sanātana informed Him about the exchange, and the Lord loved him for this and thanked him. "You are intelligent enough, and you have now exhausted all your attraction for material wealth." In other words, the Lord accepts a person for devotional service only when he is completely free from all material possessions. The Lord then told Sanātana: "It would not look good for you to be a mendicant and beg from door to door with such a valuable blanket on your body. It is contradictory, and people would look on it with abhorrence."
"Whatever I am doing to become free from material attachment is all Your mercy," Sanātana replied. The Lord was very much pleased with him, and they discussed spiritual advancement.
