Hari Om. Pranams.
Here is my reflection -
To be able to 'see' world as projection of 'Self' we first have to 'know' what 'Self' is. Currently our understanding of 'Self' is muddled up with our body, mind and intellect. The moment somebody utters word 'know' we think of it as an 'objectified experience' different from us. We start making efforts to understand it 'intellectually', 'emotionally'. What we really need to know is we can't know it that way. We need to stop all our efforts to know it as an object. Thus when mind is not preoccupied with anything, we will be ourself and we will 'realise' our own Self.
Ishavasya Upanishad says "All this, whatsover moves in this universe, including the universe, itself moving, is indwelt or pervaded or enveloped or clothed by the Lord. That renounced though should enjoy." Pujya Guruji while explaining this verse said that just understanding that everything is pervaded by Lord is not enough, you should cover this entire world with the "vision of God (knowledge)", that means look at this world as Lord only.
We normally exclude ourself when we say world and understand it as "what we perceive outside". However in Vedanta, world is "anything that is known to us as 'this' '(as an object)". Our BMI is also 'this' so it comes under world. Everything in world is moving and changing. Ja means jayate, ga means gacchati, coming and going is world but in between we have illusion that it is 'ta' tishthati that 'it stays' and that is why we give reality to it. Just like in ocean, waves rise and fall, bubbles come and go, froth happens and vanishes but they are not separate from ocean similarly world is not separate from Self. We see plurality because of giving reality to upadhis(names and forms).
Anywhere our sense organs go, mind goes, intellect goes, that is Lord(Self) this vision we need to cultivate.
