After looking at some other sikhi sites all that can be concluded is shabad is Guru.Shabad is Naam. The Dhuni /sound produced on its[Naam] recital is to be listened to consciously and it becomes the disciple. The listening of the voice of Guru makes the consciousness meet the Guru; Naam simran. There would be a time , may be after long period, when the chell starts listening to the eternal 'shabad' i.e all pervasive infinite wisdom.; the true Guru..It makes a perfect sense.
