Besides, I also have a few questions about action. I have been struggling to find the answer on whether action is required at some point or you could simply resonate with the right vibration without any action besides focusing. Lastly, I question about how I access infinite intelligence and how I can attain answers for my questions.”
I find it interesting that you think you need to know all of Abraham's teachings because Abraham has only one teaching and that is "get happy". Abraham calls the rest “a dog and pony show” – ie., examples to help us understand better why getting happy is important and how we can get happy even when we do not have everything we want. Abraham explains in many different ways because people understand in different ways.
I recommend starting out with a simple process or thinking a little bit differently than what you’ve been used to and keep adding slowly – because altering existing beliefs is a process that can take time. Don’t expect immediate results – although immediate results are possible, but looking for results actually keeps them at bay. That’s what Abraham explains in the Panama Canal Analogy.
As far as action is concerned - of course there is action involved - but it is not action as in hard work - it is inspired action and that means being in the right place at the right time so that you can receive that expensive thing you wanted or meet that special person you wanted to meet, or get referred to the person who becomes instrumental to your getting the job you always wanted. Abraham says that there is no point in taking action until you have cleaned up your vibration and got to a happy place upon the subject of your desire without taking score. I heard Abraham say that action was the way we enjoy our creations at a physical level, whereas thought, specifically focused thought is the way we create our experience. Positive thinking leads to positive creation or grid filling in and negative thought leads to negative creation or grid filling in.
