There arises a need, a desire, a lust for change.
This feeling is being offered and accepted (or discarded) producing the motivation for construction.
You run through different scenarios or possibilities of how this change would look and/or feel, but it's still imaginary (definitely not trying to downplay this part of the process, but the thought is not fully realized in the possibility of the material yet).
Now the desire, the attraction to the thought now, builds until there is no other option, but to make a decision and take action.
This act of decision brings down that otherworldly intent into the realm of manifestation.
But roadblocks arise. Usually based in self criticism invoking fear of said change/decision.
And self criticism is a useful tool, but not if you attempting to create.
In the beginning that is.
Self criticism should be employed after the process (keep in mind that some amount of analysis should be employed during the decision making process, but do not allow the logic destroy the passion that initiated this).
Imagine, do, and embrace.
If you pay attention to this cycle you begin to understand how events and things appear, or disappear.
It's when you make a decision and take action that reflects or is alignment with, the initial spark, the emotion, the imagination, this is when the doors of possibility swing open.
Through the experience of acting on both ends of this process, you can bring both modes of consciousness together.
The results of action in the material helps clarify and sharpen the connection to the immaterial realms.
And guess what, if it doesn't work the first time, good. Learn from the experience, figure out what went "wrong" (blessings in disguise), and go again.
Approach things in this manner, and then consider that this earthly realm of material and desire might actually be a good place to uncover that sanctuary of divine meaning...
