According to Osho, intensity is the inner unity that arises when all scattered desires converge into a single flame. It is centripetal energy - being wholly one, undivided, centered - in contrast to ex-tensity's fragmentation. In danger, love, or meditation, thoughts drop, the crowd of impulses becomes an individual, and such total concentration opens the way to fulfillment and God.
It’s when everything inside you points in one direction, so you feel completely one and fully present.
