I think it is essential sometimes to go on retreat, to stop everything that you have been doing, to stop your beliefs and experiences completely, and look at them anew, not keep on repeating like a machine whether you believe or do not believe. You would then let fresh air into your mind. That means that you must be insecure, must you not? If you can do so, you would be open to the mysteries of nature and to things that are whispering about us, which you would not otherwise reach; you would reach the God that is waiting to come, the truth that cannot be invited but comes itself.
