Here’s an interesting quote by William Walker Atkinson:
“As in the case of physical magnetism, is found that the average person colors his personal atmosphere by the character of his mental states, or rather by the predominant color of his mental attitude, without any special effort on his part. The degrees of color – not its particular kind, remember, but its degree of force – depends upon the degree of mental activity of the person. The person of inactive thought, ideas or feeling, will have an almost colorless personal atmosphere, while the person of the active mind will display a marked degree of thought-color therein.
We find here, also, the second class of persons, who, while not fully understanding the nature of the power, or the processes of projection, nevertheless manifest a high degree of thought color and power in their personal atmosphere. This strong color and power results from the fact that such persons are usually individuals of a high degree of feeling or idealism – that is to say, they experience strong feelings, on the one hand; or else have strong mental ideas of anything in which they are interested – or perhaps both strong feeling and strong idealism.
The strongest color and power manifested by persons of this class, is found in persons who take a strong interest in things. This strong interest really combines the two elements of feeling and attention, respectively. Feeling is a strong mental element; and attention, you will remember, is a direct application of the will. So, it follows, that such persons must strongly project their mental states into their personal atmosphere, although unconscious of the same, and without a deliberate employment of the will for this purpose.
But, here, as in the case of the physical magnetism, the strongest and most powerful effect is produced by the individuals who understands the process, and who consciously and deliberately project their thought into their personal atmosphere, where it joins and is vitalized by their physical magnetism, so that its full effect is manifested upon those who may come within its field of influence.”
