M, the passage you've quoted reminds me of the section in my workshop on Placing Intent. Perhaps "Placing Intent" and Faith mean similar things.  As I teach it Placing Intent is an area of consciousness tht has a specific feeling and if one experiences this feeling while expressing a desire theres a lot more power behind fulfillment of that desire.

I use the "silly little finger bending exercise" to teach about placing intent. the concept is that everything we do requires that we place intent. so even bending one's finger must be preceded by the feeling of placing intent. we normally do this so seamlessly that we don't consciously experience the feeling. by focusing our attention the act of bending our finger we can "capture" that feeling. Many describe this feeling as a strong knowing that the finger is going to bend. sounds a little like faith doesn't it?

Doubt was a problem for me too until I discovered how to use it to learn more aabout placing intent. I came to the understanding that if I was feeling doubt as I placed intent for something I desire I am actually placing the intent for both my desire and my doubt to manifest. before I understood this I let the manifestation of my doubt cancel the intent for fulfillment of my desired thing.

lets say I place intent to get a loan to buy a new car. as I'm placing that intent I think, who am I kidding? with my low income no one in their right mind is going to lend me that much money.

I walk into a car dealership and sure enough the guy says no way would we loan you money with your low income.   at that point I have a choice.
I can say to myself, see, I knew this was never going to happen!  and making that statement cancelled my intent to get the loan. no matter how many dealerships I go to they'll all say no. If I say to myself instead GREAT! I just remembered feeling doubt as I placed my intent for the loan and my doubt just Manifested! this means the process of placing intent is working. Now I know the loan is coming. I just need to keep going to dealerships and one of them is going to give me the loan.

thats how I'd suggest dealing with doubt. just understand that if I feel doubt while placing intention, I'm placing intention for both to happen.

I also describe another area of consciousness I call Pure Doubtless Intent.  in my view if one learns to experience this feeling and can cause themselves to feel it while expressing a desire, moving mountains would be no big trick.  walking on water would be no big trick either.

how does one learn to do this? in my view its done by practicing placing intent. being aware of what you're feeling as you express your desire and paying attention to how your desire manifests. its a process that builds confidence or faith if you like. I believe that if one practices that practice will lead to experiencing the feeling of Pure Doubtless Intent. from that point its just a matter of learning to re-experience that feeling while expressing a desire.
