According to Osho, in 'Who am I?' the questioner and the answer are the same; the very act of seeking obscures it. Persist in inquiry not to collect answers, but to exhaust them until the question itself drops. In that questionless silence, knowing happens—you don’t get an answer; you are the answer.
The one asking “Who am I?” is the very one you’re trying to find; when the questions fall silent, you just know by being.
