An article from my former website, Otherworld Journeys, that was published on 7th March 2012.
Here, in this realm, light is impenetrable but it has limits. Its intensity, its power, is built on Love and can only be amplified by Love. Love seeks to expand. Where there is self-absorption there is darkness.
In our dimension, and some others, the nature of darkness enables it to block, shape, diffuse and deflect light and the Darkness has taken full advantage of this even so far as to appear to absorb light. Light has limits. The nature of darkness is to contain.
