The dialogue in this section is worth describing carefully, because it shows the Gurus' method under pressure from an articulate opposing tradition rather than in the open.
The Nath yogis were a serious and well-organised movement with a technical vocabulary, a body of practice and a claim to attainment that could be demonstrated. They were not a straw target. The composition presents them asking direct questions, about lineage, about attainment, about the practices that produce it, and the answers come back in their vocabulary rather than around it.
What the answers refuse is the premise that attainment requires withdrawal. The claim made is that the same thing is available inside ordinary life, among a household and a trade, without the apparatus and without leaving. That is the position the whole volume takes, and here it is argued rather than asserted, against interlocutors who are given real questions to ask.
The wider significance is that this is one of the few places in the Granth where another tradition is present as a voice rather than as a subject. The volume is generally uninterested in polemic; it addresses religious professionals frequently but rarely names a school and almost never stages an exchange. The exception is instructive: when the Gurus did argue, they argued in the terms of the people they were arguing with.
