A thought-wave or vibration thus conveys the character of the thought, but not its subject. If a Hindu sits wrapped in devotion to Krishna, the thought-waves which pour forth from him stimulate devotion in all those who come under their influence, though in the case of a Muslim, that devotion to Allah, while for the Zoroastrian it is to Ahuramazda, or for the Christian to Jesus. If such a thought-wave touches the mental body of a materialist, to whom the very idea of devotion in any form is unknown, even then it produces an elevating effect, its tendency being to stir a higher part of his mental body into some sort of activity, though it cannot create a type of undulation to which the man is wholly unaccustomed.
A point of great importance, of which the student should take careful note, is that a man who habitually thinks pure, good and strong thoughts is utilising for that purpose the higher part of his mental body, a part which is not used at all by the ordinary man, and is entirely undeveloped in him. Such a one is, therefore, a power for good in the world, and is being of great use to all those of his neighbours who are capable of any sort of response. For the vibrations which he sends out tend to arouse a new and higher part of their mental bodies, and consequently to open before them altogether new fields of thought.
We may take the matter a little further still. A man who day by day is definitely and carefully thinking is not only improving his own thinking powers and sending out helpful thought-waves into the world around him, but he is also developing and improving mental matter itself. For the amount of consciousness which can be brought into the brain is obviously determined by the degree to which the atoms of matter can respond, i.e.,, to the number of spirillae in the atoms which are vivified and active.
Normally, in the ordinary physical atom at the present stage of evolution, there are four of these seven spirillae active. The man who is capable of higher forms of thought is helping to develop further spirillae in the atoms, and, as these atoms are continually passing in and out of his bodies, they are available for absorption and use by any other person who is capable of using them. High thinking thus helps the world’s consciousness by improving the very materials of thought. There are thus many varieties of mental matter, and it is found that each variety has its own special and appropriate rate of vibration, to which it is most accustomed and to which it most readily responds.
A complex thought may, of course, affect many varieties of mental matter simultaneously. The general principle, underlying the effect of thought on the mental body and also that of feeling on the astral body, is that evil or selfish thoughts are always comparatively slow vibrations of the coarser matter, while good, unselfish thoughts are the more rapid undulations which play only in the finer matter. The power of the united thought of a number of people is always far greater than the sum of their separate thoughts; it would be much more nearly represented by their product. Hence, it is exceedingly beneficial for any city or community that there should be constantly meeting in its midst a number of people who are capable of generating thoughts at a high level.
