All knowledge is hinged on right seeing.
We can say creation is full of lit doorways. These may be doors into higher levels, higher stages, or new vistas. But to see those doorways, we have to be standing in the right place, in the right perspective. If we’re around the corner, we don’t see it. But if we move into right perspective, right seeing, the lamp lights the door.
There is a readiness needed for right seeing. We might call this a security for the Divine so it remains pure. But this is also for yourself so you can approach when the physiology can handle it. Each doorway is a transformation, an upgrade, a milestone.
When consciousness is dark, empty, or the void, this indicates a shadow. The lit doors are overshadowed by the density of awareness. When that density (inertia, tamas) is refined and becomes clear, we find consciousness is effulgent. Even deeper, we find it is the light of the Divine filtering through self-aware consciousness.
As we move into right seeing, consciousness becomes fullness, richness, brilliant. In time, this infuses all levels of our being and we become that fully.
