One day Govinda Singh asked his teacher Guru  Nanak about the importance of the Guru. “The
better you become as a disciple, the better you will understand about the Guru,” replied Nanak. He
then gave a jewel to him and asked him to take it to the market to get it priced by various people and
then bring it back. A flower seller offered Govinda one rupee; a fruit vendor offered him three apples;
a petty goldsmith offered him a hundred rupees while another jeweller offered him a thousand
rupees. One of the best jewellers offered him twenty-thousand rupees while the best jeweller in
the town told him, “This is invaluable. Don’t sell it.
for any amount.”
