"As it was taught: 'And you shall love the Lord your God' which means that you shall make the name of Heaven beloved. One should do so by reading Torah, and learning Mishna, and serving Torah scholars; one should be pleasant with people in conversation and in business transactions. What do people say about such a person? "How fortunate is the one who learned Torah"… It says "one should be pleasant with people" in business transactions and in conversation, which means that being pleasant with people brings about that the name of Heaven is pleased…However, the name of Heaven is not pleased with those people of unpleasant speech etc., despite their reading and learning.
