Why the veil?

[Minyatur]

Or perhaps uncover the mechanisms that prevent you from accessing beyond the veil and your own desires that manifests them.

It is kind of hard to work out as much of your true self is hidden within your unconscious and is there for you to uncover. Ultimately there are most likely things to let go of, but the roots of them are for you to seek within yourself.

Is that something (uncovering the mechanism) that takes a force of will and gut-wrenching determination?

In my case it was curiosity.

You were fortunate. My seeking is all fear-based. And now I can't open up at all on the meds I'm on. Unless that's just a belief.

Perhaps they can make it harder, but I do not believe that something you totally stop you from doing so. 

I have never sought out of fear, so I do not know what it is like. I do have faith that one day it will all make sense to you, and that you will understand why you wanted to experience what it is that you are experiencing.
