One can never have the same experience twice because one is never the same person twice. Between the first experience and the second, even if one hour has passed, you are no longer the same man and you can never reproduce identically the same thing. If you take care to become more conscious, more sincere, more concentrated, the experience you have will be different, but it may be deeper and more clear. But if you cling to something you have had and want to reproduce the same thing, you will have nothing at all, because you can’t have the same thing and you are in a state in which you refuse to have a new experience, for you are attached to the past one. And usually when one has had an experience which was a revelation, something altogether important, one doesn’t want to leave it, one is afraid of not having it any longer, and so, in this movement of clinging to something, one prevents oneself from progressing and puts oneself in conditions in which one can’t have the next experience.
