Each Initiate has their own journey.  If the seeker cannot access the Light, then they should look to their hearts and wonder why:-

1)   Am I too greedy for the Light and not letting everything unfold in its own time?

2)   Do I feel unworthy?

3)   When I sit to meditate, am I always open for whatever happens?

4)   Is there something on my mind that needs to be addressed?

We all bring something to the table, so to speak:  it is impossible to be completely neutral.  A pure, clear, giving seeker who just wants to let go of their troubles, will be the one who gets the most from this amazing journey.
