Naanak guroo na chaytnee man aapnai suchayt
Chhutay til boo-aarh ji-o sunjay andar khayt
Khaytai andar chhuti-aa kaho Naanak sa-o naah
Falee-ah fulee-ah bapurhay bhee tan vich su-aah

English Translation
O Nanak, those who do not think of the Guru, and who think of themselves as clever, shall be left abandoned in the field, like the scattered sesame. They are abandoned in the field, says Nanak, and they have a hundred masters to please The wretches bear fruit and flower, but within their bodies, they are filled with ashes.
