Do thoughts have a physical form?

Your every thought upon being evolved passes into the inner world and becomes an active entity by associating itself—

Coalescing, you might term it with an elemental—that is to say with one of the semi-intelligent forces of the kingdoms. 

It survives as an active intelligence—

A creature of the mind's begetting for a longer or shorter period proportionate with the original intensity of the cerebral action, which generated it. 

Thus a good thought is perpetuated as an active beneficent power—an evil one as a maleficent demon. 

And so you are continually peopling your current in space with a world of your own, crowded with the offsprings of your fancies, desires, impulses and passions—

A current, which reacts upon any sensitive or any nervous organisation, which comes in contact with it in proportion to its dynamic intensity.
