A thoughtform is a manifestation of mental energy, also known as a tulpa in Tibetan mysticism. The thoughtform is also one of the expressed or visualized means of Samyama, a particular system of teaching or doctrines, often embodied as a set of vows or commitments. Recited mantras are essentially thoughtforms representing divinities or cosmic powers, which exert their influence by means of sound vibrations.
Definitions have been suggested for thoughtforms, such as that of an image held in the mind of a practitioner which aids in the manifestation of intention. It has also been proposed as an agency of psychic effect which exists and takes form in the pre-physical realms of existence, which acts in accord with the intent of its creator.
It connates a homunculus or foundation of awareness, or an instantaneous observer and observed duality. Homunculi appear in various theories of cognitive philosophy and psychology to account for different facets of conscious self. They are created by every individual at every moment, and in some formulations they are a constant manifestation of everyone at every moment, possessing a will of its own.
Thoughtforms are said to have two effects, a radiating vibration and a floating form. They are divided into three classes – those which take the image of the thinker, those which take the image of a material object, and those which take a form entirely of its own, expressing the inherent qualities in the matter which it draws around it.
It has been theorized that the effects of music, emotion and color strongly influence thoughtforms.
