Leaving aside whether there is such a state as enlightenment and whether nirvana is enlightenment or its equivalent, I believe one should always question one who promises “the” path and doesn’t just offer “a” path that has served the one offering teaching or access.
Of course, other than potential issues in any community that makes such exclusive promises, one is always free to taste and explore and reinterpret the “the” as “a.”
It’s rare that I feel the need to check the weather before leading my practice group into savasana, but tonight I did. Knowing how long it would take the last person to get home, I checked again as everyone gathered their things. There was just enough time if we did not tarry.
