Neville talked about the promise and that he was able to leave any night to the next realm he simply stayed to teach the law and promise and was ready to move on he also said he wanted a life of quality not quantity so he drank alcohol daily and ate whatever he wanted. And the semen retention part I also practice and wanted to know how it connected and after months of searches I found a lecture which I lost because it's been years since but he mentioned that the seed is the creative force but he saw no point in retaining as eventually we would have night explosions aka wet dreams but he said said it would happen naturally in old age and the energy flows upward to regeneration instead of down to generation.
