Buddhism also asserts that the spiritual journey is unique to each individual. Therefore, of course, it cannot be held, circumscribed, limited, or even ultimately judged by any institution, tradition, or extended authority. The unique journey that lies before us does not exist in any text, external person, or religion. In fact, it does not yet exist at all, but only lies ahead of us, to be discovered, literally, as we go. Thus it is that the spiritual journey cannot in any way be preconceived or predetermined; it is not humanly constructed or fabricated. The journey to ourselves is truly a journey into the unknown, a setting forth onto a sea that has never before been sailed and never before been fathomed or mapped.
