His true worth was assessed during discussions, but upon becoming a guru, he became arrogant or engrossed in his position, losing his original self.

This couplet wisely suggests that when we get too involved in debates, trying to prove our point or compare ourselves, we risk losing our way. If we then assume the role of a 'guru' or an expert in these discussions, we often become burdened by the 'man' – which symbolizes the heavy weight of ego, attachments, or superficial knowledge. It means that getting caught up in intellectual battles and believing ourselves to be masters can make us lose sight of deeper truths, leaving us weighed down by our own perceived importance and getting lost in the trivial.
