Similarly I have noticed the confusing interpretation done by most of the scholars of third pauri 'daida dey lendai thak paie jugha jugantar khaie khaei' as the great giver keeps on giving, while those who receive grow weary of receiving or interpret as something similar to it when Guru Nanak very clearly dimisses in first stanza the ritual, 'bhukhia bhukh na utri - to eat as much as one can to satiate one's hunger. Guru Nanak said that no matter how much one eats, after sometimes the hunger will comeback. Gluttony brings nothing but more gluttony or something similar to it then how come one becomes weary of receiving it when gurbani further tells us 'trishna virlai ki hi bhuji reh'. Further how can we consume/eat His gifts which are not eatable?
Ek OnKaar Sat Naam
Sahni ji, this is how I understand Pauri 3:
"There are countless different understandings of the Creator, but none knows the limits or nature of the Creator.More and more understandings are provided by more and more preachers.Those who follow have always accepted stories. The followers of such sermons eventually tire of them but The Creator keeps on leading people to search and sets the route.
One is inwardly content when one realizes the futility of searches for purpose of life and accepts the Creator alone can lead one to solutions. The Creator will do this of His own accord."
I don't think "gifts" relates to anything material; from preceding lines I guess it is to do with the different ways in which people conduct their searches for God/the Truth. They tire of them, and then start afresh, as God has implanted this idea in them (the inner Guru/Sat Guru) to find Him.
