Prayer can be an experience which nourishes a person for many subsequent years. We spoke of the necessity of petition to God. Suddenly one of the teachers stood up and began sharing with all those present a prayer experience which he had had some dozen years previously. After a short time his voice began to shake. A person can live his prayer and relive it for years thereafter.
Every prayer has the potential to serve as such an experience.
At the conclusion of his prayer a person should feel as though he is a changed person. It is also the most sublime of pleasures. Both a necessity and a pleasure. That was enough for him. At that moment he attached himself to Rav Kook forever.
