What is the ruling on Neuro-Linguistic Programming (NLP)?

The consensus of several scholars' fatwas has warned against Neuro-Linguistic Programming (NLP). The reasons for this warning can be summarized as follows: this field has philosophical and doctrinal roots; it brainwashes Muslims with ideas that advocate for the unity of existence. Moreover, its methods are illusory, and it is forbidden to rely on them. This field also contains many negative aspects from which people must be warned. These fatwas have been supported by scholars specializing in Islamic creed and contemporary ideologies, as well as by experts in psychological sciences and psychiatry.
