As i know from other peoples, there is many monastries in traditional buddhist countries where Vinaya is not well respected (money, internet etc) so unless to search on the place a good one or go to a one who is recomendet to you.you wrote : "Anyway i prefere western monasteries with it Discipline."
Can you explain that please?
