The quote emphasizes that simply discussing the concept of enlightenment or truth is not enough if people are unable to perceive it. Carl Jung criticizes theologians for focusing on proving the existence of spiritual light rather than helping people recognize their own potential to see it. He points out that many individuals live in a state of blindness, unaware that they have the capacity for insight and understanding. Instead of just praising the light, which represents knowledge or awareness, the priority should be on teaching others how to open their eyes to this light. This approach encourages personal growth and freedom, as it empowers individuals to discover and embrace their own insights. Ultimately, it suggests that the journey to understanding is more important than the mere acknowledgment of truth.
