1) Are Hypnosis recordings helpful in changing negative beliefs to positive?
Tom: That depends on the individual and how they interact with the hypnosis techniques on the recording. The will/intent to change at the being level must be present within the individual. If hypnosis is used as a tool to focus one's attention upon the positive, then it could be helpful if the long term result is that one's level of fear is reduced and remains that way even without hypnosis. If hypnosis causes no permanent shift from fear toward love at the being level, then it serves little purpose. Don't expect hypnosis or any other technique to fix you -- first you must be ready to fix yourself -- then most any tool that suits your personality and belief structure can facilitate the growth process.
2) Will a person be denied access to a certain job etc if it would lead to higher entropy instead of less?
Tom: Yes, that could indeed happen. It is not necessarily so but such "choreography" is not uncommon. This sort of manipulation is not based upon an assessment of the individual's entropy alone, but rather on how the average entropy of the system will be affected (those two considerations are often very similar if other's lessons are not involved, but may occasionally be very different). That this "help" is given by the larger consciousness system is why most people who have a sense of the bigger picture say that "things generally work out for the best". Or, "look for the silver lining"
3) Could you expand further on one of your answers explaining why guides would use fearful situations as teaching experiences?
Tom: Case 1: If a person is too fearful to safely and profitably experience NPMR directly (doing so would more likely raise the entropy of their consciousness than lower it), then the best way to filter out those folks and prevent a regrettable experience is to give them a fear test before letting them loose in NPMR.
Case 2: if a person needs to get over certain fears to move forward, and if outgrowing those fears is within their reach, then creating fearful situations that allow and encourage the individual to overcome the fear would be in order. Growth rarely takes place with something catalyzing the process. Unfortunately, without pain or discomfort to prod us to make changes, most of us are completely content with a feel-good status quo.
