উপোসথ হলো বৌদ্ধ দিবস পালনের দিন, যা বুদ্ধের সময় (৬০০ খ্রিষ্টপূর্বাব্দ) থেকে এখনও বৌদ্ধরা পালন করেন।For a description of the contemporary practice of the Uposatha in Thailand, see Khantipalo (1982a), which is also excerpted in this article below. Kariyawasam (1995), ch. 3, also underlines the continuity of the ancient uposatha practice in Sri Lanka: "The poya [Sinhala for uposatha] observance, which is as old as Buddhism itself, has been followed by the Sinhala Buddhists up to the present day, even after the Christian calendar came to be used for secular matters. Owing to its significance in the religious life of the local Buddhists, all the full-moon days have been declared public holidays by the government."The uposatha day is sometimes likened to the Judeo-Christian notion of the Sabbath. Pali English dictionaries that define "Uposatha" as "Sabbath," are Buddhadatta (2002), p. 63, and PED(Rhys-Davids & Stede,1921-25), p. 151. For an example of the Uposatha being equated with Sabbath by a modern Buddhist master, see Mahasi (undated), p. 2, where he writes: "For lay people, these rules [of discipline] comprise the eight precepts which Buddhist devotees observe on the Sabbath days (uposatha) and during periods of meditation." Harvey (1990), p. 192, also refers to the uposatha as "sabbath-like." বুদ্ধ শিখিয়েছিলেন যে উপোসথের দিন হলো "অশুচি মনের পরিচ্ছন্নতা" এর ফলে অভ্যন্তরীণ প্রশান্তি ও আনন্দ।Thanissaro (1997b); Anguttara Nikaya 3.70: Muluposatha Sutta. এই দিনে, সংঘের সাধারণ ও নিযুক্ত সদস্য উভয়ই তাদের অনুশীলনকে তীব্র করে, তাদের জ্ঞানকে আরও গভীর করে এবং সহস্রাব্দ পুরানো সাধারণ সন্ন্যাসীদের পারস্পরিক আচরণের মাধ্যমে সাম্প্রদায়িক প্রতিশ্রুতি প্রকাশ করে। এই দিনে, সাধারণ অনুসারীরা পঞ্চ বা দশ উপদেশ রাখার জন্য সচেতন প্রচেষ্টা করে। এটি বুদ্ধের শিক্ষা ও ধ্যান অনুশীলন করার দিন।   তথ্যসূত্র    উৎস    Buddhadatta Mahathera, A.
