They're trying to find the Love (God) that they think they are separate from.
They are looking everywhere that this Self/Love/God does not exist, outside of themselves and away from presence, also in the past and future.
So everyone in all their seeking is really trying to locate and get back the sense of 'I Am' that they covered up when they started seeking. How will they find 'home' away from home?
So all the gathering and getting and taking and stealing and earning and succeeding and achieving and efforting and hunting and acquiring and buying and so on ... it's all the world's attempt to reclaim what it deeply believes it has LOST.
And what it believes it has lost is God.
It seeks to replenish that loss through all these external avenues, using illusions and forms and objects and falseness and idols and special relationships etc, to try to 'fill up' that sense of emptiness - the lack of God - the lack of True Self. Because God and True Self have been covered up, and that's what has made everyone believe they are in need, and therefore need to seek.
The truth is that God is not missing, and everyone's True Self is eternal and still exists just as God created it.
It's all just a matter of unconsciousness - ego - standing in the way of awareness, deceived by illusions and appearances, attempting to assert that God is lost and therefore finding 'other stuff' will replace Him.
Nothing can replace love because love cannot be removed. But that also means love is not lost. It's just hidden.
Its our job to reveal and open up to and accept and reclaim our inheritance. What is already ours. And what can never be undone.
You still are. God still is.
