Such "objective methods" may make hypnosis more acceptable to the general public, but they also limit it to shallower depths. Wang Wu-shih pays special attention to the depth to which Eastern religious devotees delve "to awaken to the truth": "When people repeatedly enter the subconscious to explore, their quest goes beyond the level of treating emotional problems and disease to probing at the very nature of life."
然而一套「客觀方法」雖較能「昭公信」，不過在催眠能達到的深度上則較有限，王悟師便特別注意到東方個人靈修：「人不斷往潛意識探索深入後，早已超越了治療情緒和疾病的層次，而深入生命的探索。」
