there is no such thing as beautiful or ugly in this cosmos. everything of this cosmos is beautiful &  everything of this cosmos is ugly. everything is the way that it is .it is ur perception that judges it beautiful or ugly.for boy, lets imagine the most beautiful girl u have ever seen, most charming, radiant that stunned in u first place.imagine that picture in ur mind. now, imagine that girl if she is bald. her face is still same but just i have removed hair from scalp.now how much beautiful is she.altering a bit makes something beautiful and ugly to ur perception.
           now did u realize, your perception is illuding u. if u wear green colored glass, u see everything green and u if u wear red color glass, u see everything red. but everything is the way it is .it has not changed. its actually your programmed subconscious mind that it is perceiving the external world.the BELIEF and bullshit rules that society imposed in ur brain makes u the way you become and the way you start viewing the world.
& it is the basic principle of origin of many pschiatric diagnosis.
i bet many new psychiatric diagnosis can be prevented if u learn to reprogramme ur mind. everyyear DSM is addding many new psychiatric diagnosis.what is the origin of this. ur mind is ruling u, u r not capable of ruling ur mind.
