Getting rid of yeshus

The Alter Rebbe had a chosid, by name of R’ Avrohom Kalisker, who was blessed with a great mind, and was a very big lamdan. Once, in his youth, his father complained to the Alter Rebbe that his son has yeshus. The Alter Rebbe said: ‘Bring him to me!’ When the boy came to the Alter Rebbe, the Alter Rebbe asked him a question in learning, and then asked the youth if he thought that it was a good question. When the boy responded in the affirmative, the Alter Rebbe answered his own question, and asked Avrohom if he felt it was a good answer. When he replied that it was, the Alter Rebbe went on to ask a question on his answer, and once again asked the boy for his opinion on the question. This went on for a few questions and answers, until, suddenly, the Alter Rebbe exclaimed to him: “Everything I say you say is good, this is not what I consider knowing how to learn!” With this the Alter Rebbe was mevatel his yeshus.
