this quote above, is from the book of Job. it is also quoted in a play in which i once played the lead role, that of Job. Job's patience has haunted me since my youth, questioning the infinite divine principal with my impatience while "walking up and down in the earth."
some believe that the infinite has within it good and bad, light and dark, chaos and order. whatever one may believe, spiritually or intellectually the undifferentiated natural law contained, yet not bound, within the unified field has all that one needs to sustain you.
to tap into that field of infinite possibility, one need only to listen to the silence. stop thinking. (not easy yet within reach, with practice, like through meditation) whatever the mind or heart can conceive you may achieve.
this is the principal oft quoted, "let go and let God." trusting in the divine to formulate all of the facets of ones desire, without assistance from you, to achieve your goal.
this i have done, "let go and let God," to achive my hearts desire. don't think about it. don't cloud your daily activities with thoughts of achieving your goal. it is already written, once you turned your attention to it if only you would release the "monkey mind" from it's chattering and allow the divine to work it's magic.
alas, i am human. 
that thing called "free will" compels me to try to direct the divines forces, bend them to my will, i think. i fret as do we all. then i remember the quantum mechanics of infinite possibility, the omnipotence of the divine, and draw closer to my intention, my goal by releasing it to the divine. (the reason for the tattoo on the back of my neck, a constant reminder of her omnipotence)
hence my question about doors.
just a little impatient that's all.
"one door closes... " where the heck is the other door that's supposed to open? lol
it teaches me that sometimes we focus too much on the obvious.
