Upadēśa Undiyār verse 16: a practical definition of real awareness

In the article I posted a couple of days ago, Is there any difference between being self-attentive and sitting down quietly in meditation?, I ended by quoting and explaining verse 16 of Upadēśa Undiyār:

வெளிவிட யங்களை விட்டு மனந்தன்

லகமிதுதா னெங்கெழுமென் றாய்ந்தே — யகவுருவை

யுன்கணரு ணாசலனே யோர்.

Isn’t ‘how the ego arose’ a permissible question, considering that Bhagavan has explained it in Uḷḷadu Narpadu himself, this question of how the ego came into existence? Can a good understanding of how the ego came into existence also help us in our attempts to destroy it with vichara?”, in reply to which I wrote:
