To what extent are post-hypnotic suggestions embraced by the deep subconscious, to be acted on?

Interestingly, this rarely happens because the deep subconscious has a certain level of skepticism when being instructed by third parties. It has a broader purview and it will not immediately embrace and follow instructions given, unfailingly and without question, but rather will have some degree of selectivity in what is acknowledged and what merits follow up. Keep in mind as well that while the deep subconscious is aware of what the conscious mind is experiencing, so what a hypnotist relays to the person in trance will be heard by the deep subconscious, but it cannot talk to the conscious level of the mind, and so will lack the wherewithal to act on such suggestions, and that is the major impediment for that sequence of events to transpire. So there can be some influence on the deep subconscious, but it is weak. For one thing, the deep subconscious is not used to having the conscious mind tell it what to do, so it is a passive witness to much that happens but can only act on its own initiative and creativity, which is modest, so there is a lack of understanding and motivation to take something like a post-hypnotic suggestion to heart because it will not feel the suggestion is being made to its being, as a separate component of the mind. So this makes for little of practical value in getting anything useful out of post‑hypnotic suggestions directed at the deep subconscious—it is not a workable approach via the conscious mind or the upper subconscious level.
