Life without the Naam is a sheer waste:

Forgetting the Word, one wanders in delusions, leaving the roots, one clutches at the leaves and gets nothing. 

Guru Nanak, Asa M1

Drunk deep in love for the self and the children, oh Nanak! Without the Naam, existence is a wasteland. 

Guru Arjan, Maru M5

One returns not to see his children, friends and the household, Kabir saith: without contacting the Naam, life goes in vain. 

Kabir, Kedara Kabir
