I am trying to understand the structure especially the importance of shalok(highlighted in red) .Like in Paudi the last verse basically is the essence of paudi so in similar lines what does shalok convey.

O Nanak, those who do not think of the Guru, and who think of themselves as clever,
ਛੁਟੇ ਤਿਲ ਬੂਆੜ ਜਿਉ ਸੁੰਞੇ ਅੰਦਰਿ ਖੇਤ ॥
