According to Osho, yes—keval-gyan has ripened: it is the fruition where both the known and the knower vanish, and only pure knowing remains. Nothing is left to be known, and no one left to claim it; there is just the capacity to know. This non-dual, contentless awareness is the essence of keval-gyan.
It’s when the person who knows and the things to know disappear, leaving only clear knowing itself.
