From
The Sufi Path of Knowledge by Chittick, Ibn al ‘Arabi says:
Nowadays most people interested in the spirituality of the East desire the "experience," though they may call what they are after "intimate communion with God." Those familiar with the standards and norms of spiritual experience set down by disciplined paths are usually appalled at the way Westerners seize upon any apparition from the domain outside of normal consciousness as a manifestation of the "spiritual." In fact there are innumerable realms in the unseen world, some of them far more dangerous than the worst jungles of the visible world. No person familiar with the teachings of Sufism would dare lay himself open to such forces...
And, then, there is this that Laura discusses in
The Wave I (which I strongly agree with Aiming's suggestion that you read that series if you haven't already) speaking of the experience of a woman who is talking about The Beautiful Lady:
She puts the robe around me and then my mind separates from my body. I can look back and see it lying there. Then we go up through the ceiling, pop out the roof, and fly into space. One night the Lady took me back in time. We were in a foreign country and the people wore old-fashioned clothes. The Lady took on the appearance of a beautiful woman in a blue robe. She performed miracles for them..."
Suddenly Ann's face turned ashen and she asked to be excused. Her scream of pain was heard from the bathroom where she had taken refuge. When Ann came out, she was sniffling and holding her abdomen. The Lady had savagely attacked her for revealing that down through history, creatures like the Lady have taken the form of saints. They then use the gullibility of humankind to misguide and misinform people so that they believe they are seeing miracles performed. Ann begged the newsman to delete that portion of the interview." (Osborn, 1982)
I think that it is very important to know about the forces that inhabit other dimensions and densities because they are not all wonderful spiritual beings that want to guide and help us. Knowledge protects and ignorance endangers could not be more applicable than in cases like these.
Laura discusses these things, and much more, in her
The Wave series.
