It is also argued that in one life the soul would fail to acquire the varied experience which is necessary to form a well rounded mentality of understanding. Dwarfed by its limited experience in the narrow sphere occupied by many human beings, it would be far from acquiring the knowledge which would seem to be necessary for a developed and advanced soul. Besides this there would be as great an inequality on the part of souls after death, as there is before death--some would pass into the future state as ignorant beings, while others would possess a full nature of understanding. As a leading authority has said: "A perfected man must have experienced every type of earthly relation and duty, every phase of desire, affection and passion, every form of temptation and every variety of conflict. No one life can possibly furnish the material for more than a minute section of such experience." Along this same line it is urged that the soul's development must come largely from contact and relationship with other souls, in a variety of phases and forms. It must experience pain and happiness, love, pity, failure, success--it must know the discipline of sympathy, toleration, patience, energy, fortitude, foresight, gratitude, pity, benevolence, and love in all of its phases. This, it is urged, is possible only through repeated incarnations, as the span of one life is too small and its limit too narrow to embrace but a small fraction of the necessary experiences of the soul on its journey toward development and attainment. One must feel the sorrows and joys of all forms of life before "understanding" may come. Narrowness, lack of tolerance, prejudice, and similar forms of undeveloped consciousness must be wiped out by the broad understanding and sympathy that come only from experience. It is argued that only by repeated incarnations the soul is able to realize the futility of the search for happiness and satisfaction in material things. One, while dissatisfied and disappointed at his own condition, is apt to imagine that in some other earthly condition he would find satisfaction and happiness now denied him, and dying carries with him the subsconcious desire to enjoy those conditions, which desire attracts him back to earth-life in search of those conditions. So long as the soul desires anything that earth can offer, it is earth-bound and drawn back into the vortex. But after repeated incarnations the soul learns well its lesson that only in itself may be found happiness--and that only when it learns its real nature, source, and destiny--and then it passes on to higher planes. As an authority says: "In time, the soul sees that a spiritual being cannot be nourished on inferior food, and that any joy short of union with the Divine must be illusionary."
