(Cloud) as shadow was expressed through the Baha’i Writings that physical reality is but a shadowy reflection of the world of the spirit: Abdu’l-Baha Say: “know thou that Kingdom is the real world, and this nether place is only its shadow stretching out. A shadow hath no life of its own; its existence is only a fantasy, and nothing more; it is but images reflected in water, and seeming s pictures to the eye.”
In another reading of this line might be the following: “The clouds which provide me with shade and comfort from the heat of the sun would be destroyed by the heat of tribulation in the path of your love.” In other words, the tribulations or calamities, though outwardly grievous, burn away the veils that conceal the world of the spirit from my understanding.”
So don’t build castles upon this shadowy world that when the night comes and sun covers its face there would be no shadow and whatever we built upon it and/or upon water during the ‘day-time’ will be vanished! So as the ‘oil’ of life is burning into the lamp of body use it for reaching, stretching out to the ‘light’ instead of dropping all on the surface and/or water to make some temporary forms and/or pictures!
I have one word to say to those who don’t believe in dreams; ‘DREAM!’ We might see something in dreams that we can’t see them in day-light because we are living in the shadow of the world of reality and only dreams and visions can take and giving us a glimpse of the reality of all things!
