This essay features religious lessons of buddhism regarding the Three Poisons(三毒), referencing 「Sipjipum(十地品)」 of 『Avatamsaka-sutra』 as the main text. The essay is composed of two parts. First, description of Three Poisons in early versions of the script is introduced in 2nd chapter of the essay. Three Poisons described in here consists Greed(貪慾), Anger(瞋恚), and Ignorance(愚癡), which are three main factors that disrupts one’s state of mind. They are referred as “Poisons” because not only they are the sources of all disruptions, they also harm people’s mind akin to three vipers. The Script empathizes that the cause of Three Poisons starts from the stimulation of eyes, the first of six sensory organs, where it progressively stimulates Realm of Vision(色境), the Perception of Vision(眼識), and finally simulates the Five Components of Self(五蘊) so that they are triggered simultaneously to create disturbance. There is also a clear explanation regarding what fuels Three Poisons to thrive. There are spark of greed and spark of anger from sensory stimulation, spark of ignorance from mental aspect, and finally, sparks of birth, aging, illness, death, sorrow, anguish, suffering that empowers the flame of Three Poisons. Our senses are stimulated primarily by outside source, but what truly evokes Three Poisons is that the fact that we see, hear, smell, taste, feel only as much as we are stimulated, so that we discriminate, judge, and eventually cling to it. From this, it is clear that the Three Poisons are evoked by workings of 18 realms(18界)[Six roots + Six factors of consciousness + Six cognitions] The key point is, therefore, that the salvation of all beings is to elimination of greed, anger, and ignorance. The Third chapter covers Three Poisons described in 「Sipjipum(十地品)」, and their solutions according to each section of Ten Grounds(十地). As the result, various methods of teachings described in detail were found in every stages of Ten Grounds. The solutions clearly appears to be the upmost cure for Three Poisons, the root of all evil. Also, it should be noted that in 『Daśabhūmikasūtra-śāstra(十地經論)』, the commentary book of 『Avatamsaka-sutra』, states that the purpose of teaching Ten Stages lies in curing Ten Disabilities - which are, in fact, many forms of mental affliction and idle thoughts. We, who lives modern days, should still be aware of the harmful effect of Three Poisons mentioned in the section of Stage of Joy(歡喜地), and only way to achieve emancipation from it is to practice the teachings of Ten Stages. In short, all methods against Three Poisons listed in teachings of Ten stages are concluded into Seven Buddha’s Prohibitions(七佛通戒偈): “Do not commit all evil, and practice all goods. keeping one’s mind pure by oneself, that is the teachings of every Buddha.”
