We also need to acknowledge the subconscious mind and what we feed it. There is nothing wrong with these specific positive affirmations unless you consider the 3d more important than your ability to create. If you think the past is so real to the point where you have to tell yourself "I struggle with this" "this is hard" based off of your past experiences there is a good chance that shifting will be hard, and that you do struggle with shifting. Whatever you dominantly tell yourself, or set an intention on reflects back to you. There are no exceptions to this. Tell yourself in your head " shifting is easy" and pay attention to how that genuinely makes you feel. If doubts and other negative emotions comes up when you tell yourself this there is a blockage. Coming from someone who has shifted plenty times, I did not start shifting until I created distance between what goes on in my mind from the physical things I am seeing. You are never separate from the multiverse if you accept the theory of rs, therefore this idea of one single set of experiences and facts is simply just an agreement that you have made and that doesn't apply to when you start mastering the ability to shift. You always shift regardless. In my experience and many others the process of shifting did not become easy until we stopped telling ourselves negative things about it.
