If we have been right so far, we have arrived at the position that Nature is a Personal Being in process of realising an ideal operating within herself. We have now to satisfy ourselves as to the character of that ideal. What is the full ideal working in the whole of Nature we cannot possibly know. We can only know so much of it as can be detected with our imperfect faculties on this minute atom of the Universe on which we dwell. We cannot be sure we have even discerned the highest levels of the ideal. For there may be higher beings than ourselves on the planets of the stars, and among those higher beings higher qualities than any we know of, or can conceive, may have emerged. Love is the highest quality we know. But love in any true sense of the word--love as a self-conscious activity--has only emerged with man, and man has only appeared within the last half-million of the Earth's four or five hundred million years of existence as the Earth. We cannot, therefore, presume to say what is the ideal in its highest development for the whole of Nature. But from our experience here we can see what that ideal is up to (what for us is) a very high level, and we can make out what is apparently its fundamental characteristic. I obtained my best conception of it on the evening I left Lhasa at the conclusion of my Mission to Tibet in 1904, when I had an experience of such value for determining Nature's ideal, and, for me at any rate, so convincingly corroborative of the conclusions which others who have had similar experiences have drawn from them as to Nature's ideal, that I hope I may be excused for relating in some detail the circumstances in which it came to me. These circumstances, though not the experience itself, were somewhat exceptional. I was at that particular moment at the highest pitch of existence--that is to say, of my own existence. I had had an unusually wide experience of the wild countries of that most interesting and varied of the continents--Asia, and for that reason had been specially selected for the charge of a Mission to Tibet. However ill-qualified I might be for other tasks, for this particular business of establishing neighbourly relations with a very secluded and seclusive Asiatic people, difficult of approach both on account of their natural disposition and of the mighty mountain barrier which stood between them and the rest of the world, I was esteemed to have peculiar qualifications. My comrades were also men selected for their special qualifications--one for his knowledge of the Tibetans, another for his knowledge of the Chinese, another for his knowledge of geology, and so on. The troops engaged were selected for their experience in frontier warfare, and each man had had to pass a medical test. We were at the top of our physical fitness and ripe in experience.
