According to Buddhistic teaching, there are two worlds, so to speak--the one ruled by the law of causality, the other over which the law of causality has no power. A Buddhist would say that "the man who applies to the strictly unconditioned predicates such as being and non-being, which are used properly enough of the finite, the conditioned, resembles one who attempts to count the sands of the Ganges or the drops of the ocean." With much the same sort of reasoning Jesus referred to the mysteries of the kingdom of heaven when addressing those who had eyes and did not see, and ears and did not hear. In view of the apparent fact that the human body has reached its utmost limits of development, as a physical organism, there seems to be a thinkable probability that it will eventually, by a devolutionary process and by the atrophy of its present clumsy and imperfect organs, return, step by step, during the gradual cooling of this planet, to the condition of the psychic life of a simple cellule, and ultimately to the unconditioned; back, as Huxley puts it, to the indefinable latency from which we arose; or, as Carlyle expresses it, "pass stormfully across the astonished earth from God and to God." Starting from the simple cellule, we see, in a way, how "Tanha," or the desire to extend the scope of activities, has persistently striven in this direction until the ultimate possibilities of the development of physical organism have been reached in man. This highly-differentiated organism has become more and more sensitive to pain, more and more dissatisfied with its limitations; and man, recognizing these limitations, desires to abandon them altogether. Consequently, he seeks refuge in the hope of a future life, where limitations will no longer curb and embarrass him, and where he will cease to be subject to pain, passion, and sorrow. Jesus and Gotama have indicated how by the suppression of this "Tanha," how by detachment from the things of the world, we can approach that simple cellular life-stage which is on the road to Heaven, Nirvana, and the Unconditioned. It is easy to realize how much pleasanter it would have been for us all if the simple cellule from which we spring had not been so persistently ambitious in the direction of activities. Its relatively prescribed functions suggest a most desirable condition of peace compared to that "unrest which men miscall delight." Human life is but a drop in the ocean of organic existences on this planet--about 1,500 millions only among countless myriads of beings. It cannot, then, be accounted strange in a world containing so great a variety of organisms, with their varying tastes and needs, that man should find much that is distasteful and unsuitable to him which is pleasant and acceptable to other beings. The vulture feasts on carrion loathsome to man. Man partakes of food at which a rhinoceros would shudder.
