During one of his sojourns

During one of his sojourns, the Guru gave his students a thin book to learn from while he was away for about a week. On his return, the guru asked them all whether they had learned the lessons he had given them. All answered positively except his favorite student. He had not done the lessons.
The teacher asked him again in the hope that maybe there was some communication problem or may be he had not heard him well. The student again answered that he had learned only one line from the book. The teacher blasted him saying “ONE WEEK AND ONLY A LINE” and again the boy had the impudence to say that he had learnt just one line.
The Guru then smacked the boy across his face but the boy kept his face down in complete submission to his Guru. The guru's face was still livid with rage, thinking may be the boy was joking at his expense and again he asked his favorite student “how much did you learn?” “only one line” answered the boy. The guru got ferocious and his voice roared and resounded in the ashram and even the other disciples got frightened. The Guru asked him to get out of his sight and the boy, wiping away his tears, went to a secluded corner of the Ashram while the rest went for  their duties.
‘Time’ it is said is the best healer!
In a couple of hours as the Guru retained his calm and was handling other matters, he thought over the incident again and felt sorry for the boy as he had never slapped any boy in his ashram and that too when the boy was his favorite.

He sent for the boy and the boy stood before him humble in his manner. The guru placed his hand on the boy's head and gently asked him, “My dear, show me what is the one line you have learnt?” The student opened the book to the first page and the only line he had taken over a week to learn was “Learn to control and be a master of your anger”. Seeing this Guru's hand trembled and the book slipped out of it. Guru's heart filled up with remorse as it was his duty to teach the students about life but in a week, the boy had learnt a lesson that he (the Guru) failed to learn. The Guru embraced the boy hiding his tears.
The student taught his own teacher and the student became the father of “MAN”. The boy grew up to be known as Dharmraj Yudhisthir and the guru was Guru Dronacharya.
Yudhisthir did exactly what needs to be done today. He took the lessons (idealism) from the book and brought it into real life and gave them a form in real life. No wonder the epithet “Dharmraj” became his title of address.
The lesson to be learnt is that one must honor the Guru under all circumstances. If Guru Dronacharya had not gotten angry, Yudhisthir would never have learnt the importance of controlling his anger.
In the momentary loss of sanity that Dronacharya took upon himself, he showed his other students and generations to come, the folly of losing one's temper even though he may have to bear the ignominy of being a short tempered flawed preceptor, Dronacharya is a Guru in the truest sense with no desire for anything and Yudhisthir is a student, ready to sacrifice everything for the Guru.
Truly it is said in the Vedas






May the Guru be ever blessed!
