The outcome of following the required steps in the contemplation is just this experience; otherwise, we have not attained anything from the contemplation. In other words, the entire purpose of the contemplation in front is to produce this final experience. When we clearly experience no-self, we are at the stage of starting the practice. How do we practice? By maintaining this state of mind as long as possible without distraction — ten seconds, twenty seconds, a minute, two minutes, the longer the better. Such is the practice of no-self.
