The Kaminker Rebbe once resolved to devote a whole day to reciting Psalms. Towards evening, he was still reciting when a messenger came to tell him that his mentor, the Maggid of Tzidnov, wanted to see him. The rebbe said he would come as soon as he was finished, but the messenger returned, saying that the Maggid insisted that he come immediately. When he arrived, the Maggid asked him why he had delayed. The rebbe explained that he had been reciting Psalms. The Maggid told him that he had summoned the rebbe to collect money for a poor person in need. He continued: "Psalms can be sung by angels, but only human beings can help the poor. Charity is greater than reciting Psalms, because angels cannot perform charity."
