In the quote from Mark Nepo's "Seven Thousand Ways to Listen," the author encourages readers to resist the temptation of debating the nature of truth, comparing it to the futile argument of whether it is day or night. This perspective reminds us that there are always different realities and truths depending on one's viewpoint and circumstances in different parts of the world.
Nepo suggests that instead of getting caught up in these disputes, we should strive to seek a deeper understanding of truth, one that transcends our individual experiences. This universal truth, akin to the sun, is continually present, and by coming together, we can access and appreciate this higher reality.
