Happened to see more details about 16th pauri at sikhnet.com discussion forums dated July 12. In that, author said - "So when you begin, through the power of your own practice, to recognize the Creator within you - something happens. You start to live in your own Jot, your own Divine Light. And then that Light shines from you in a way that other people can see. And in that Light - people trust you and you become a Royal Servant to everyone. This is what "Panch" is. It is that state of consciousness we achieve after doing the work of listening so deeply that we have conquered our own fears and misconceptions, and out of that fearlessness of recognizing the Light of God within ourselves - we become a Living Light to others on the earth."

As per that discussion, Panch doesnt lead to meaning 'five'. Anyway, I think, I need to read both the explanations in detail again. However, the progressive and analytical thoughts are certainly appreciated.

Best Regards.
