The way I currently see it is that the whole transmission thing is about call/response that is utterly spontaneous, purposeless and impersonal (it's not even that but I need to use words!). The seemingly separate parts of the Universe are constantly receiving and sending out transmissions and thus affecting each other in ways that human mind is not equipped to fathom.
On a very basic level, for example, this morning something that I call my cat came up to my bed and meowed, and something I call my body made a sound. My mind then goes and says: "there is a separate being called cat that belongs to a separate being called A and because I love her I am going to reply to show her that I care". If the mind is not believed that my response is directed by me for a specific purpose then all I see is this spontaneous, purposeless and impersonal call/response mechanism. On a bigger scale, this call/response can also be seen at the level of the planets - the Earth turns around the Sun and changes its axis (response) because of the the Sun's gravity (I believe it's called precession).
I believe that the net of call/response relationships is much more complex and intricate than the examples above because the whole Universe is doing this call/response thing with itself (and that includes cat/A and Earth/Sun call/response). Therefore transmission from teacher can or cannot have a certain result depending on a myriad of interactions between seemingly separate parts of the Universe.
Obviously, if we got rid of all the concepts then even that is not true but, as i said, I need to use words, therefore, inevitably, I need to tell lies!:-)
