When one invokes the names of God, one forgets his limitations and impresses his soul with the thought of the Unlimited, which brings him to the ideal of limitlessness. This is the secret of life's attainment.
Man is the picture or reflection of his imagination. He is as large as he thinks himself, as great as he thinks himself, as small as he thinks himself to be. If he thinks he is incapable, he remains incapable; if he thinks himself foolish, he will be foolish and will remain foolish; if he thinks himself wise, he will be wise and become wiser every moment; if he thinks himself mighty, he will be mighty. Those who have proved themselves to be the greatest warriors, where did their might come from? It was from their thought, their feeling; 'I am mighty.' The idea of might was impressed on their soul, and the soul became might. The poet had poetry impressed on his soul, and so the soul became a poet. Whatever is impressed on man's soul, with that the soul becomes endowed, and that the soul will become.
