In this second stage, Man soon becomes perplexed. He finds problems that demand an answer, but as soon as he thinks he has answered them the problems present themselves in a new phase, and he is called upon to "explain his explanation." The mind, even although not controlled and directed by the Will, has a wonderful range, but, nevertheless, Man finds himself traveling around and around in a circle, and realizes that he is confronted continually by the Unknown. This disturbs him, and the higher the stage of "book learning" he attains, the more disturbed does he become. The man of but little knowledge does not see the existence of many problems that force themselves before the attention of the man of more knowledge, and demand an explanation from him. The tortures of the man who has attained the mental growth that enables him to see the new problems and the impossibility of their answer, cannot be imagined by one who has not advanced to that stage. The man in this stage of consciousness thinks of his "I" as a mental thing, having a lower companion, the body. He feels that he has advanced, but yet his "I" does not give him the answer to the riddles and questions that perplex him. And he becomes most unhappy. Such men often develop into Pessimists, and consider the whole of life as utterly evil and disappointing--a curse rather than a blessing. Pessimism belongs to this plane, for neither the Physical Plane man or the Spiritual Plane man have this curse of Pessimism. The former man has no such disquieting thoughts, for he is almost entirely absorbed in gratifying his animal nature, while the latter man recognizes his mind as an instrument of himself, rather than as _himself_, and knows it to be imperfect in its present stage of growth. He knows that he has in himself the key to all knowledge--locked up in the Ego--and which the trained mind, cultivated, developed and guided by the awakened Will, may grasp as it unfolds. Knowing this the advanced man no longer despairs, and, recognizing his real nature, and his possibilities, as he awakens into a consciousness of his powers and capabilities, he laughs at the old despondent, pessimistic ideas, and discards them like a worn-out garment. Man on the Mental Plane of consciousness is like a huge elephant who knows not his own strength. He could break down barriers and assert himself over nearly any condition or environment, but in his ignorance of his real condition and power he may be mastered by a puny driver, or frightened by the rustling of a piece of paper.
