I can’t explain the color blue without being self-referential, though I know it’s located between violet and green on the optical spectrum. Or the power of the blues except with uninspired definitions of rhymed, simple narratives played flattened or gradually bent in relation to the pitch of the major scale. Both descriptions are sterilized to the point of meaninglessness. These two are as real as any “proven” entity, yet remain beyond the grasp of non-experiential understanding.
We bask in the glory of the senses but as a path to true knowing they are clearly quite limited and limiting.
