Naam is not the Subject of the Senses
The True Naam is invisible, imperceptible and infinite. It is being uttered day and night without a tongue. By the practice of listening to the Name, Shabd, the waves of the mind are stilled and the mind is controlled.
Guru Nanak exhorts us to attain realization of this Name.
The Naam is invisible, imperceptible and infinite; its essence is very sweet and dear. Oh Lord, bless Nanak with Your praise in all ages. There can be no end to Your remembrance.
