Most spiritual teachers are strongly against the use of any drug.
A few believe that a true mystical state can be induced by drugs, but that its value is lessened. However, there are a number of teachers who do believe in the value of MDMA, both for their own personal enlightenment and for teaching others. I also obtained comments from another Benedictine monk. Being still when taking MDMA helps you to know how to sit, it provides you with experiential knowledge. It is like a medicine.
