Three general principles underlie the production of all thought-forms:—
- Quality of thought determines colour.
- Nature of thought determines form.
- Definiteness of thought determines clearness of outline.
THE MEANING OF THE COLOURS
The table of colours given in the frontispiece has already been thoroughly described in the book Man Visible and Invisible, and the meaning to be attached to them is just the same in the thought-form as in the body out of which it is evolved. For the sake of those who have not at hand the full description given in the book just mentioned, it will be well to state that black means hatred and malice. Red, of all shades from lurid brick-red to brilliant scarlet, indicates anger; brutal anger will show as flashes of lurid red from dark brown clouds, while the anger of "noble indignation" is a vivid scarlet, by no means unbeautiful, though it gives an unpleasant thrill; a particularly dark and unpleasant red, almost exactly the colour called dragon's blood, shows animal passion and sensual desire of various kinds. Clear brown (almost burnt sienna) shows avarice; hard dull brown-grey is a sign of selfishness—a colour which is indeed painfully common; deep heavy grey signifies depression, while a livid pale grey is associated with fear; grey-green is a signal of deceit, while brownish-green (usually flecked with points and flashes of scarlet) betokens jealousy. Green seems always to denote adaptability; in the lowest case, when mingled with selfishness, this adaptability becomes deceit; at a later stage, when the colour becomes purer, it means rather the wish to be all things to all men, even though it may be chiefly for the sake of becoming popular and bearing a good reputation with them; in its still higher, more delicate and more luminous aspect, it shows the divine power of sympathy. Affection expresses itself in all shades of crimson and rose; a full clear carmine means a strong healthy affection of normal type; if stained heavily with brown-grey, a selfish and grasping feeling is indicated, while pure pale rose marks that absolutely unselfish love which is possible only to high natures; it passes from the dull crimson of animal love to the most exquisite shades of delicate rose, like the early flushes of the dawning, as the love becomes purified from all selfish elements, and flows out in wider and wider circles of generous impersonal tenderness and compassion to all who are in need. With a touch of the blue of devotion in it, this may express a strong realisation of the universal brotherhood of humanity. Deep orange imports pride or ambition, and the various shades of yellow denote intellect or intellectual gratification, dull yellow ochre implying the direction of such faculty to selfish purposes, while clear gamboge shows a distinctly higher type, and pale luminous primrose yellow is a sign of the highest and most unselfish use of intellectual power, the pure reason directed to spiritual ends. The different shades of blue all indicate religious feeling, and range through all hues from the dark brown-blue of selfish devotion, or the pallid grey-blue of fetish-worship tinged with fear, up to the rich deep clear colour of heartfelt adoration, and the beautiful pale azure of that highest form which implies self-renunciation and union with the divine; the devotional thought of an unselfish heart is very lovely in colour, like the deep blue of a summer sky. Through such clouds of blue will often shine out golden stars of great brilliancy, darting upwards like a shower of sparks. A mixture of affection and devotion is manifested by a tint of violet, and the more delicate shades of this invariably show the capacity of absorbing and responding to a high and beautiful ideal. The brilliancy and the depth of the colours are usually a measure of the strength and the activity of the feeling.
Another consideration which must not be forgotten is the type of matter in which these forms are generated. If a thought be purely intellectual and impersonal—for example, if the thinker is attempting to solve a problem in algebra or geometry—the thought-form and the wave of vibration will be confined entirely to the mental plane. If, however, the thought be of a spiritual nature, if it be tinged with love and aspiration or deep unselfish feeling, it will rise upwards from the mental plane and will borrow much of the splendour and glory of the buddhic level. In such a case its influence is exceedingly powerful, and every such thought is a mighty force for good which cannot but produce a decided effect upon all mental bodies within reach, if they contain any quality at all capable of response.
If, on the other hand, the thought has in it something of self or of personal desire, at once its vibration turns downwards, and it draws round itself a body of astral matter in addition to its clothing of mental matter. Such a thought-form is capable of acting upon the astral bodies of other men as well as their minds, so that it can not only raise thought within them, but can also stir up their feelings.
THREE CLASSES OF THOUGHT-FORMS
From the point of view of the forms which they produce we may group thought into three classes:—
