Sat Siri Akal.
Just to add one thing ........ in these four pauris, 28, 29, 30 & 31, Guru ji has used the symbols or practices or story of Yogis or mythology. And by using the same given his own view, and not of Yogis. For example, Munda, Saram, Jholi, Khintha, Danda, Bhandaran etc. In this verse also, metaphor of Maya and three qualities (associated with 3 dieties) are used. However, Guruji is giving his view of one Ekonkar using these terminologies. Same is the case of other three pauris.
So the meaning should be understood from the Guru Nanak's philosophical perspective and not from the Hindu mythology or Yogi's point of view.
