Yes its really the opposite, Law of One typically says physical vehicle.. The Law of One Search Results for ‘physical vehicle’ its mentioned 51 times..
Just to dig deeper for clarifications sake… an really how help paint a full picture of why prisoner is definitely not the case, I will include this passage.
47.8 Questioner: In our esoteric literature numerous bodies are listed. I have here a list of the physical body, the etheric, the emotional, the astral, and the mental. Can you tell me if this listing is the proper number, and can you tell me the uses and purposes and effects, etc., of each of these, or any other bodies that may be in our mind/body/spirit complex?
Ra: I am Ra. To answer your query fully would be the work of many sessions such as this one, for the interrelationships of the various bodies, and each body’s effects in various situations, is an enormous study. However, we shall begin by referring your minds back to the spectrum of true colors and the usage of this understanding in grasping the various densities of your octave.
We have the number seven repeated from the macrocosm to the microcosm in structure and experience. Therefore, it would only be expected that there would be seven basic bodies which we would perhaps be most lucid by stating as red-ray body, etc. However, we are aware that you wish to correspond these bodies mentioned with the color rays. This will be confusing, for various teachers have offered their teach/learning understanding in various terms. Thus one may name a subtle body one thing and another find a different name.
The red-ray body is your chemical body. However, it is not the body which you have as clothing in the physical. It is the unconstructed material of the body, the elemental body without form. This basic unformed material body is important to understand, for there are healings which may be carried out by the simple understanding of the elements present in the physical vehicle.
The orange-ray body is the physical body complex. This body complex is still not the body you inhabit but rather the body formed without self-awareness, the body in the womb before the spirit/mind complex enters. This body may live without the inhabitation of the mind and spirit complexes. However, it seldom does so.
The yellow-ray body is your physical vehicle which you know of at this time and in which you experience catalyst. This body has the mind/body/spirit characteristics and is equal to the physical illusion, as you have called it.
The green-ray body is that body which may be seen in séance when what you call ectoplasm is furnished. This is a lighter body packed more densely with life. You may call this the astral body following some other teachings. Others have called this same body the etheric body. However, this is not correct in the sense that the etheric body is that body of gateway wherein intelligent energy is able to mold the mind/body/spirit complex.
The light body, or blue-ray body, may be called the devachanic body. There are many other names for this body, especially in your so-called Indian Sutras or writings, for there are those among these peoples which have explored these regions and understand the various types of devachanic bodies. There are many, many types of bodies in each density, much like your own.
The indigo-ray body, which we choose to call the etheric body, is, as we have said, the gateway body. In this body form is substance, and you may only see this body as that of light as it may mold itself as it desires.
The violet-ray body may perhaps be understood as what you might call the Buddha body, or that body which is complete.
Each of these bodies has an effect upon your mind/body/spirit complex in your life beingness. The interrelationships, as we have said, are many and complex.
Perhaps one suggestion that may be indicated is this: The indigo-ray body may be used by the healer once the healer becomes able to place its consciousness in this etheric state. The violet-ray, or Buddhic, body is of equal efficacy to the healer, for within it lies a sense of wholeness which is extremely close to unity with all that there is. These bodies are part of each entity, and the proper use of them, and understanding of them is, though far advanced from the standpoint of third-density harvest, nevertheless useful to the adept."
Thank you flofrog for the the excuse to include this 
My recent achievment is using different word for confirmation, it took, lets say, about several months to become easier to use.
