Almost one hundred years ago, many people in our country were addicted to Opium and completely abandoned themselves. That’s why our country tried to get away from the damage from Opium, but unfortunately caused Opium War. Nowadays, drug abuse has become a global problem. According tot he statistics of Ministry of Justice Jan-Sep in 103 , the total quantity of drugs caughted amounted to 3826 kilograms. The damage drugs caused to the society is still going on and has not yet ceased. I have been taking part in the religious education for the people receiving rehabilitation treatment in prisons for nearly twenty years. All these years, I have been devoted to the drug prevention, hoping to seek a better way beneficial for the drug abusers and help them to start up their new life. In this research, I make use of the techniques of mindfulness combined with Tea-Chan in religious education for drug addicts in Rehab Institution. A twelve-week course named “Life of mindfulness” is designed to establish new pattern of life for the drug addicts. This course includes learning the techniques of mindfulness and experiencing Tea-Chan. Eighteen drug addicts joined in the course. They were all volunteers and accepted to join in this course after interviews one by one. In the course, participants first learned the techniques of mindfulness, then kept mindfulness diaries and in the last made use of all the techniques they had learned in so-called “Tea-Chan exhibition”. In this way, I helped them to deepen their impressions of mindfulness and planted the mindfulness seedling in their hearts. This research was intended to find out: 1) whether mindfulness could change the habitual life pattern of the participants, 2) in what aspect they changed themselves, 3) how mindfulness was applied to drug addicts in religious education, 4) the application and effects of Tea-Chan Exhibition, and 5) finally the feasibility study mindfulness was applied to the education of drug addicts in prisons. After this course, I analysed all the data collected in this course and found that if mindfulness diaries could be continued for a longer period of time, the participants could reach sobhanasadharana mentioned in《Abhidharma》:kayapassaddhi、citta-Passaddhi、kayalahuta、citta-lahuta、kaya-muduta、citta-muduta、kaya-kammaññata、citta-kammaññata、kaya-paguññata、citta-paguññata、kayujjukata、cittujjukata and could go on to viraticetasika:sammavaca、sammakammanto、samma-ajivo, and that may be the key point for them to get away from drugs after they get out of prisons in the future. My suggestions are: 1)mindfulness can be used to raise mental and physical levels of drug addicts, 2)mindfulness can lead to new life of eight Noble Truths, and 3) we should plan to promote “New Life of Mindfulness” widely.
