Belief means what a person believes to be true. In the context of religious beliefs, faith is confidence in the teachings of a religion. Faith, unlike knowledge, does not base its presumption of truth on logic. If a person believes in something, it need not matter whether it is actually a fact, that is, a provable fact. Thus, the term belief can also be a pseudonym for religion. A distinction can be made between whether a person believes in a thing completely or partially. Belief can strongly influence one's attitude towards a thing. It is also a common topic when it comes to hypnotherapy. Mistakenly, it is often said that hypnosis only works if the client believes in it. But this is not correct. At least, no belief in the sense of a religion is required. It is important that a client himself is open to the experience of hypnosis and also believes that the effect of hypnosis is possible in principle. A healthy skepticism may be present and can even support the process.
