Doubt gives a pessimistic attitude. One questions, "Will it be, or will it not be? Do I think rightly, or do I think wrongly? Am I on the right path, or on the wrong path? Shall I succeed, or shall I fail throughout life? Will conditions be better, or worse?" When there are two possibilities the earth impresses a person with doubt against the good one. He wants to conquer the good one, to have it, he desires that things should be better, but what he finds, rising from the earth, is doubt, and for his faith therefore he does not get proper support from the earth. As man does not see God, he does not look up, he only looks at the earth and wants support from there. The great lesson that the blessed ones have taught to humanity was to raise one's vision upwards and to find faith in something which is free from all doubt. Pessimism and optimism, therefore, are two different attitudes: the one looks downwards, the other looks upwards.
