The study results are as follows. First, psychological therapy based on Buddhist emptiness philosophy is in the same context with cognitive therapy which treats by changing unreasonable belief to reasonable belief. Second, client of cognitive therapy has psychological problem while psychological therapy based on emptiness philosophy includes not only clients with psychological problem but also the general public who want to solve eventual problem of life. Third, psychological therapy based on philosophy of emptiness aims at solving more fundamental and comprehensive problems than cognitive therapy. Fourth, cognitive therapy has multiple stages in treatment process and needs several sessions of consultation. But Buddha's examples show that immediate enlightenment could be obtained by only one time consultation. Fifth, cognitive therapy needs continuous management by counsellor for prevention of reoccurrence even after close of treatment In the psychological therapy based on philosophy of emptiness, autonomy of client is emphasized in that this requires practice process to deeply think, reidentify, and apply dismantlement of eventual cognition obtained from enlightenment.
