Once, a Sikh made a request before the Guru Ji, "O true King! I am grieved by the world. Eliminate the pain of birth and death. Save me from sins. I am in your protection" I am illiterate so cannot even recite or understand Gurbani.
Guru Ji said, "Brother Sikh! You are blessed that you became detached (from the world). To gain wisdom, knowledge is very important. One should get education. An uneducated person cannot understand anything.
Guru Ji asked another learned Sikh to teach that Sikh with love. The Learned Sikh started to teach him. While teaching, he taught him this line of Anand Sahib prayer, "Anand bhya meree maaye, Satguroo main paaya." (The heavenly pleasure occurred, O my mother, for I have found my True Guru).
The Sikh recited this line with love and went on reciting it. His faith increased reciting this line. After six months, Guru Ji asked the learned Sikh, "Did he learn?"
He replied, "He did not return after learning one line."
Guru Ji called for that Sikh and asked, "You were sent to learn."
He replied with folded hands, "Guru Ji! One line was enough. When the True Guru has been found, 'Anand' is gotten. " what else I could possibly ask for ?
Guru Ji smiled and said, "You are 'nihaal' (bliss). Your cycle of birth and death has been curtailed."
He has gained wisdom with this one pankti of gurbani.

He has enshrined the Name of the Lord, Har, Har within my breath of lfe, and all my doubts and sorrows have departed. I have meditated on the invisible and unapproachable Lord, through the Guru's Word, and I have obtained the pure, supreme status.
anehadh dhhun v aajehi n ith vaaj ae gaaee sath igur b aanee n aanak dhaath kar ee prabh dhaath ai joth ee joth sam aanee 1
The unstruck melody resounds, and the instruments ever vibrate, singing the Bani of the True Guru. O Nanak, God the Great Giver has given me a gift; He has blended my light into the Light. 1
