Self-suggestion is similar to hypnosis

When using the method of self-suggestion in contemplative practice (vipaśyanā-caryā) of the Buddha's Dharma, the mind consciousness must frequently suggest to the manas that the five aggregates (pañcaskandha) are false and illusory, that all dharmas are false and illusory, and that they are all the functions and operations of the tathāgatagarbha. At a certain point, the manas will give its assent, and then the self-view (ātma-dṛṣṭi) can be eliminated, thereby allowing one to unleash one's own potential and transform oneself. This kind of suggestion is similar to self-hypnosis: adjusting oneself into a relatively quiet and tranquil state, a state in which one can hear the voice within; only then can self-suggestion be carried out.

Slowly and with measured cadence, recite the aforementioned content for eliminating the self-view, guiding the manas to accept it, and allow the manas a certain buffer of time to receive the information, organize itss, whether it has experience in guiding, and whether it truly understands the principle of non-self. Such guided hypnosis can be repeated many times in appropriate settings and at suitable times. As long as the mind consciousness is well-versed in the theory, knows how to observe the manas, knows how to guide the manas, and can maintain a composed and tranquil state, then after a certain period of time, the self-view will surely be eliminated.
