In the mental body, conceptual thought is the most subtle or finest thought and occurs where thought and consciousness first conceive an idea.
Structured thought is thought that is well formed within the mental body, in visual, audible or other format.
In the emotional body, the first stirrings of types of likes/dislikes, wants/not wants, desires for or against, in response to thought or sensory income are fine stirrings of the emotional body.
As the emotion becomes strong it is experienced as a feeling and effects upon the physical body as physical sensations and biological responses. For example, butterflies in belly, impulse to smile or laugh, hormone secretions.
