We talk about many things... the spiritual search, finding God, looking for Oneness, becoming One with the Universe, seeing Spirit...
These ideas are at the core of the illusion, the core of duality, that there is "someone" who could or needs to search, find, look for, become One with, or see something spiritual...
We must start from the only obvious reality we have - the fact of our own Being, the fact that we ARE.
And from there? "Searching" itself indicates the problem - WHO is searching? "Finding" is the same, "looking", "becoming", "seeing"....
We cannot search for it because we ARE it. We cannot FIND it because it's what is doing the looking... We cannot become One with it because we already ARE it, we already ARE Oneness, looking at itself.
Like the fish looking for water, we are swimming in Oneness, immersed in Life fully each moment. And IN this appearance of Life in it's totality, thoughts arise of a "separate ME" who needs to find Life, needs to become One with Oneness.
Can you see the search itself is what seemingly creates the "need"? the "lack"? The very IDEA that there is a separate "self" needing to find Oneness?
Without using thoughts, where is there any separation? Look!
You ARE Oneness, Oneness seeing itself... you are Seeing-Oneness... Life looking at itself... any feeling, any thought, any idea, any belief, any relative label (good/bad, up/down, here/there, black/white...), any form, any "part" of the appearance is THAT, is Oneness.
Duality is the appearance, the relative perspective - Nonduality is the reality, the Absolute perspective which CONTAINS all possible relative perspectives... The appearance and the knowing of the appearance are not separate. Simply look!
And in this looking, this Oneness seeing itself, is there even the concept of "seeing"?
