What does Ra mean by "Thought Form"

[JJCarsonian]

To me thought form is everything that is not the true one. Love the great original thought, is exactly that. A thought. In most cases you can take the word distortion congruently with thought. However there is a field of magic surrounding the creation of beings using thought forms. Which most superimpose that which the subject thought form consists of. The composition of the material and how it interchangebly uses distortion, thought form, illusion. All really point to them being 'thought'. For a point of reference of what i speak, is that if you can grasp it, it is most assuredly not you.
Thought itself how we think, is a subset within Love. The original thought. The One thought contained all the potentials for every thought/choice/action. And subsequent fruit/product, expounding infinitely on itself. Free will the great reactor; through choice.

Thanks for your insight, although its absolutely correct, i believe its more philosophical than what i was looking for. I'm just wondering what Ra is referring to in the readings when he mentions the word "thought form", because he uses that term alot, and sometimes it comes across as a being living as thought (not a physical 3D body), and sometimes it sounds like an actual Physical 3D object (made from thought). This question came to mind when i was reading the following passage:

16.43 Questioner: I want to ask a rather questionable question. I may not put it in the book. I was wondering if cattle mutilations that we now experience across the country and elsewhere could be explained by you.

Ra: I am Ra. The greater part of your so-called mutilations take place according to the ways of your second-density beings which feed upon carrion. A portion of these so-called mutilations are those which are of what you may call multi-dimensional type: a thought-form construct using various parts in order to have life and being in third density.

16.44 Questioner: Where do these thought-forms come from?

Ra: I am Ra. This is a very ambiguous question. However, we will attempt to answer. Firstly, they come from the Creator. Secondly, they come from what you may call, lower astral in plane, thought. Thirdly, in construct visualization complex they reside in part beneath the crust of your planet.

16.45 Questioner: Are these one form in particular?

Ra: I am Ra. These entities may take any thought-form associated with an emotion of fear or terror.

16.46 Questioner: Are these thought-forms able to attack only cattle or can they also attack human beings?

Ra: I am Ra. These thought-forms cannot attack third-density beings.
