Reading about this topic, one can stuff one's head
with more dead weight concepts.
Before our grasping mind, trying to get one's head around it,
images get considered.
e.g.Hearing about the infinite the image of a long stretched out infinite might appear.
Do notice this is just an image and has nothing to do with what is pointed at.
Its another concept.
With the word oneness, the image of oneness as people and things merging
and blurring into each other could turn up.
Again another concept, nothing to do with reality.
And in turn these images might evoke a sense of longing for those
illusory realities, as some far out states to be reached.
This is not the way to go, it is still the mind trying to grasp.
Instead keep investigating the assumed identity.
Get clear about who and what you are.
Who are you?
