From the book "Naam or Word", written by Sant Kirpal Singh

Naam is characterized by a sweet and serene Sound Cur­rent. This Ethereal Music is going on in each individual. In fact, there is no place without It. Its Divine notes can be heard through the grace of some Master of Divine Music or Master-soul. All the scriptures of the world make pertinent references to this heavenly Harmony.

God manifested Himself as Naam – the ever rever­berating Naam,
The Vedas, Shastras and Smritis sing of Naam, times without number.
GURU ARJAN

The Naam (Sound-principle) reverberating as It is in all hearts, does not diminish or increase and is Unchanging Permanence,
Without Naam all are just paupers, and this Truth comes only from a Master-soul.
Hearing the Naam one becomes the knower of the Self, and gets all that is good and noble,
Hearing the Naam all sins drop off of themselves and one easily gets at the Truth,
O Nanak! by hearing the Naam, one's face shines with glory,
The beloved of the Master is ever in contact with the Naam.
GURU NANAK

Then the Eyes of the blind shall be opened, and the Ears of the deaf shall be unstopped.
Then shall the Lame man leap as an hart, and the Tongue of the dumb sing:
for in the wilderness shall waters break out, and streams in the desert.
ISAIAH

For now we see through a glass, darkly; but then face to face:
now I know in part; but then shall I know even as also I am known.
