As a matter of fact neither of these students is superior to the other, but each is great in his own line. In one set, you have an example of automatic mentation in Mathematics, Science and Geography; in the other in Literature and Art. But suppose the first set tried to master Literature and Art and the second grappled with Mathematics and Science, each would then be practising actual concentration. In each set the active function would be exercised and will-power would develop on both sides. Do you see? Occultists say that all power results from the continual exercise of active mentation and all weak-mindedness is the direct outcome of this wool-gathering, castle-building, inattentive habit which is an extension of passive mentation into useless channels of thought-force. Conscious attention concentrates and even specializes mental energy as the sun-glass concentrates and intensifies the heat of the rays of the sun. Focus your full attention upon the thing to be done, take a keen interest in its accomplishment to the exclusion of all else, and you will obtain wonderful results. The man of developed, concentrative power holds in his hand the key to success, with the results that all his actions, voluntary or involuntary, are pointed to the accomplishment of his object. Remember therefore in conclusion: (1) Concentration is perfect attention consciously directed to a given point of achievement either objectively or subjectively. (2) Concentration is consecration. "What ever you do, do it with all your might. Do one thing at a time and do it well." By concentration is meant the directing of all your energies along a special line of achievement. For instance, if you would be a perfect Yogi, you must concentrate, concentrate, morning, noon and night, at all times, along that line of endeavour. You must study all the vast literature on Yoga, Psychology, Metaphysics, Mentalism, etc., and form your own synthesis on same. You must think hard and work hard for Yoga. "Genius is the power to bear infinite pain." Nothing ought to be too great a sacrifice, including your own life, for the right understanding and achievement of Yoga. All half-heartedness, all insincerity, weakens your nature, and weakness has no place either in heaven or in hell. For the half-hearted man is a traitor unto the Divine within him and must pay dearly for his treachery. SUBJECTIVE CONCENTRATION--HOW PRACTISED. This is a vast subject. If you practise earnestly my instructions on Thought-Control, Will-Culture, and take the Meditation Exercise I am going to give you, you will realize greater strength than average humanity. But you must study and think hard for yourself before any considerable benefit can be derived from even these. Remember please, you alone can teach yourself through intuition. Intuition is tuition from within. Follow strictly the general rules I give you and you cannot but unfold your Inner Soul Vision which includes intuition in its fullest sense.
