Without Naam we are dead to true values of life:

He alone wakes up to the Reality whom God may so desire and meditates on the Word of the Master. Oh Nanak! They indeed are dead who do not commune with Naam, only a devotee doth live.

Guru Amar Das, Ramkali M3

The peerless human body is cast by virtuous deeds, and they that contact not the Naam destroy their very self, why do they not die who forget the Naam, for without the Naam human life is of no value. 

Guru Arjan, Gauri M5
