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.”
When I was out at lunchtime to run an errand, I crossed paths with the neighbor (or visitor) wearing this shirt. I asked if I could photograph him. He seemed a bit taken aback, but posed for me when I said that I would only photograph the quote. After all, anyone who would walk around Capitol Hill with a Bayard Ruskin quote on his chest would likely want to motivate as many people as possible to think about that quote and act accordingly.
