When Nanak was a boy of seven, he was sent to Gopal Pandha to learn Hindi. The teacher told Nanak to read a book. Nanak replied, "What will it avail to know all and not have a knowledge of God?" Then the teacher wrote the Hindi alphabets for him on a wooden slate. Nanak said to the teacher, "Please tell me, sir, what books have you studied? What is the extent of your knowledge?" Gopal Pandha replied, " I know mathematics and the accounts necessary for shop-keeping." Nanak replied, "This knowledge will not in any way help you in obtaining freedom." The teacher was very much astonished at the words of the boy. He told him, " Nanak, tell me something which could help me in the attainment of salvation." Nanak said, "O teacher! Burn worldly love, make its ashes into ink and make the intellect into a fine paper. Now make the love of God your pen, and your heart the writer, and under the instructions of your Guru, write and meditate. Write the Name of the Lord and His praises and write, 'He has no limit this side or the other'. O teacher! Learn to write this account." The teacher was struck with wonder.
