One of the most interesting aspects of spiritual development is that of "spiritual sight." Perhaps this may better be described as a kind of "spiritual knowing," though I think there are often visual components that appear in our minds to help us better understand the experience.
Oftentimes in Christianity, we hear of "spiritual blindness" and such, and it's interpreted in a kind of metaphorical fashion: "spiritual blindness" translates to "not acquiescing to our conceptual framework of Christianity as the Ultimate Truth."
But the spiritual blindness is something much more immediate and real- there's a very real kind of unseen realm(s) that we cannot perceive without dedication to meditation and specific kinds of training.
This is so important for mystics to understand, but in truth, this is important for virtually all Christians to understand. Christianity is mysticism. Christianity can't truly be separated from mysticism except by distortion and misunderstanding.
There are finer points that can be argued- and indeed, have been argued- about the relationship between Jesus and the Christ and so on, and I'll leave those arguments up to theologians who are competent in both reasoning and mysticism, as I've chosen to focus on the mystical path forward. Perhaps one day I'll be able to circle around to philosophy and theology and separate what's real from what's not, but I'm not there yet.
Until recently, I would've not paid attention to the concept of spiritual blindness and darkness, but meditation has definitely shown me there's more out there and more going on at any given time than most of us are aware of.
Let us continue to dedicate ourselves to Christ and to meditate on the Divine.
